So I've been looking at some 1GB players, mainly the iAudio U2, and was wondering if anyone has some recommendations? I haven't really bothered with the portable mp3 players before, but is there a significant difference in sound quality between players? Or is it more like comparing recievers where they may sound 'different' in the same price class, but not necessarily worse? I basically just want one that sounds as good as possible and is as small as possible, without much concern for battery life, heh.
