Sony Portable Mini-Disc Player/Recorder (MZ-R500PCNAVY)
Excellent product if you are okay with low volume.
I bought this product about 6 months ago and have tried everything I could think of to record MDs so I could listen to them at a fairly high volume. I was hoping I could get the same volume that I got from my Sony Discman. Instead after making MDs and listening to them at the gym, I can hear people talking around me, I can hear the gym sound system blaring over my MD player. I just could not get enough volume out of this thing to get me pumped so I gave it to my girlfriend and she loves it. I guess she doesn't need music to get going at the gym. Bottom line is, buy this mini disk player only if you want mini sound.
