Recommend inexpensive MP3 player?

[Reid Priedhorsky <reid@reidster.net>]

Hi folks,

I would like to get an MP3 player to use with my Lenny box. My specs are
few but perhaps odd:

- Cheap.
- Used OK.
- 512MB or larger OK.
- Uses AAA or AA batteries, preferably 2.

Do you all have any suggestions?

Many thanks for any help,

Reid
