It really pays to do not only your research but also spend time testing the one you will buy. I used to use an M-Audio MicroTrak. It's fine in most respects, but the display would go dark just as you needed to see it in the wings of the stage where it was dark. It had an odd pushbutton that you could not know if you had pushed it, and a delay in the screen so you couldn't see if it did what you want. Neither of these things would be apparent by reading any manual.

I now use a SONY http://www.amazon.com/Sony-PCM-M10-Porta...7495&sr=8-1

The transport buttons are great. The screen is very readable and clearly shows what I need. It is expandable in memory but comes with 4 GB built-in. It has a speaker so you can double-check that you have the right song loaded. The built-in mics are good. It plays and records WAV as well as MP3, which I think is important. Of course, being a recorder as well, it's probably overkill for what you need.
