Just added to my bounty of Sony products.(actually bought 2 months ago but forgot to post)

CD-walkman D-CJ01

Cd player that plays mp3s on cdr\rw and normal music cds. Comes with a power supply or you can use your own AA batts. Line out to stereo if you want. Bought at www.abtelectronics.com for much lower than listed on their website.
