The Boy

Hi, I'm looking for any suggestions on buying my first acoustic guitar. I have looked over a few used guitars on craigslist, but I was not sure how much I should pay or what I should be paying for. The first guitar I saw for sale was a $100 Fender Starcaster with new strings, picks, a case, and a tuner (Fender Starcaster Acoustic $100 OBO). Another is a entry level classical acoustic for $35 with a gig bag and a set of strings (Classical Acoustic). The third is an Ariana acoustic guitar for $75 with a starp, gig bag, and string set (Ariana Acoustic Guitar). Any suggestions or opinions anyone could give me would be a great help, since I'm looking to purchase a guitar before the next week is out. Thank you in advance for any advice you have.
