It doesn't make any sense to me why a person would need to use two separate solutions in conjunction unless they were going for a particular effect, like recording to analog tape for a specific sound.
Modern DAWs are every bit as capable as a standalone recording system. Assuming a decent audio interface is used, there's no reason not to record in the box. I don't see the point of the extra steps and equipment that would be required to record separately then import into the computer for processing when you can just record into the computer with software that is specifically designed to do this (Pro-tools, Sonar, any recording software really) and eliminate the external solution.

The only requirements are that there is a decent audio interface with the amount of inputs and preamps that the person desires. These things are designed specifically for this purpose. We're not talking about a standard computer sound card. These are recording audio interfaces, and any studio in the world that records with a computer is using one.

Anyway, to the OP, if you want to scale up to your 150 limit, you can, however you should just be aware that there's only so much you're going to get out of the equipment and hardware itself in terms of end result. You can buy a 3,000 dollar Apollo 16 interface or a 100 dollar M-Audio interface, and either way you'll still be limited by your knowledge and experience in regard to recording and mixing, and also your other gear in the signal chain. The best preamps in the world won't matter if for instance you're recording with bad microphones, poor mic placement, and utilizing improper EQing and compression in the mixing stage.

So, my recommendation would be to first address the main issue, which is having a decent enough audio interface that will not stop you from obtaining good source material. You would not be able to work toward getting great recordings by using an onboard PC sound card. The Alesis interface will not hinder you, and it will allow you to utilize the rest of your budget for addressing other issues.
For instance, what will you be mixing on? If it's a bad pair of headphones instead of studio monitors, then you're likely not going to be making good recordings and mixes that actually translate well outside your own system, as you won't be hearing the recording as it truly is. If you're planning on other people listening to your recordings, then this is a pretty important consideration.
Another consideration is the quality and ability of your recording software. If you're using Audacity or Garageband, for instance, you might not be able to do some of the things other software allows you to do.
And so on...

Above all, you should remember that there is no magic bullet. Good recordings are a combination of gear, ability, technique and experience. It makes no sense to go out and buy the most complicated and expensive solutions and not address the other factors. So the best approach is to buy a reasonably priced solution that lets you effectively work on the other factors that go into making a good recording.
And if you ever get to the point where you become skilled and experienced enough that you can demonstrate that your gear is what's holding your efforts back, then that is when you upgrade. Not the other way around.

An apt analogy would be a person buying an expensive Les Paul to learn how to play guitar, thinking that the Les Paul is going to make him play better.
I know that you're just trying to rectify a bad recording due to a bad equipment situation, but I think it's important to look at it the right way so that you can be reasonable about your expectations.

alright so for Freebase - I will be a little bit more specific and provide more details
I use the AKG D-5 microphone, with CUBASE.
and to record my Bass guitar I use a regular cable with my bass which is an ibanez S550.
I do metal vocals for almost a year now, and I got nothing but compliments and positive responses out of metalheads who enjoy my style of music (deathcore, metalcore, death metal) I dont really have a studio all I have is my room, I can get a windscreen and a mic stand but can somebody please explain to me with detail how can I get the best recording quality for the cheapest price? how to set up a home studio for cheap? what equipment do I NEED and what equipment is recommended?

i have a lexicon alpha interface which is good and easy to use. does everything i want and i can add effects to the library by downloading them. the one thing i don't like about it is it doesn't have any midi i/o or a preamp for a condenser mic. i have heard a few people say the focusrite Scarlett 212 is good it has all the connections and a preamp with phantom power.
i got my lexicon from cash converters they seem to have a lot of music gear, something about people seem to hock a lot of music gear. i get most of my stuff from there have bought a couple of good guitars and always 1/2 the price and in good nick.
Ive looked on eBay a few times and they have some good interfaces at decent prices. a lexicon alpha goes for $99 some will post for free or very cheap. another thing to consider is a good mic. no matter how good your equipment may be the mic can let it all down. i am using a couple of dynamic mics which are OK but i have to turn the gain up a fair bit to get some volume when recording and this can bring out some hiss. Ive found that a condenser mic is better esp for vocals as it has a cardioid diaphragm which is more sensitive and gives a clearer and truer sound for vocals. you need a pop filter and a preamp with phantom power. you can also use them for acoustic instruments and you will need to have a quiet place to record as they will pick up any other noise coming in.
i also have a Yamaha mixer going into my interface which gives me more lines and the preamps. if your on the road and want to record a band then a laptop is needed for the comp based recording if you are using the stand alone equipment then im not sure what you need to get. i would imagine some sort of multi track recorder or a mixer and the recorder. there are probably equipment out there that has it all in one as well as capability to connect digital. using the computer based recording you have a lot of software that can act as mixers/effects in fact anything you want and is cheaper. stand alone i would think would not be cheap and not sure if it would have the same capabilities. another thing is some say that using analog equipment gives a better sound more live and authentic as apposed to digital sounding artificial and techno.
