Yo, does anyone here own a mp3 cd player? I'm looking for the best mp3 cd player. I'm stuck between these three models: 1. Sony D-NE710 ATRAC3/MP3 CD Walkman Portable Disc Player 2. Panasonic SL-MP70 Portable CD/MP3 Player 3. Sony D-NE510 ATRAC3/MP3 CD Walkman I'm not sure which to get. Any Advice?
