Anyone tried using a digital voice recorder for recording acoustic guitar ideas? Growing up I used a portable tape recorder to preserve musical ideas (voice and guitar) and though the quality was not great I could hear each note and pick out most of the chords later.

I am considering buying a digital voice recorder. They range from about 20-30 bucks including shipping on ebay to hundreds of dollars.

Anyone been using a cheaper digital voice recorder to record ideas away from you computer or main recording device? I have heard that some particular units compress so much that you cannot make out musical notes.

Thanks for any advice.
