I'm looking for something that I dont need to use with a computer. More of a portable personal recording device that I can use to keep ideas and record me and a friend of mine. We are just doing acoustic stuff but we are coming up with so much we want to be able to just record the stuff on the fly as opposed to playing something, then trying to remember what we did and write it down. Looking for something under or around $100, new or used, and that will provide decent recording and playback. Not looking for anything crazy, just something of decent quality.
