digital voice recorders
 

I know that digital voice recorders aren't supposed to be used for recording piano music, but because of my low budget (maybe around $100) I think I'll have no choice but to use one. I did record some pieces using a digital piano setup at my friend's house but I don't want to bother him every time I want to record.

I've tried a friend's Olympus and it turned out to be pretty decent (forgot to check what model), but I wanted to see what else is out there, or if there's any other alternatives that aren't too elaborate/ won't break my bank account ^_^'.

Any suggestions?
