Good digital voice recorder for songwriting tool
 

I'm looking into buying a digital voice to archive song ideas with, I think I'm losing a lot of material without one. I know that the sound quality is a problem all around, but it would just be for rough demos, although it'd be nice to have functionality for simple recording techniques like punch-ins, etc. I'm liking the Olympus series so far...what do you think?

Have you checked out the Zoom H4:
H4 Handy Recorder

Looks pretty sweet, sounds good, and I think has multitrack recording..

I use an iriver mp3 recorder and it sounds pretty good just for ideas.
