Summary: Got a "like new" used one for an unbelievably low price and I'm in love with it's great music playback and how you can pick the sound enhancement from a wide selection. Probably the BEST mp3 player I've had in a long time (and I've used almost all name brand players - ipod, zune, zen, sansa, sony,...
