Polaroid PMP120-4 4GB USB 2.0 MP3 Digital Music/Video Player & Voice Recorder w/1.8" Touchscreen (Black)
Not the worst, but do not recommend it.  Like others said, it's not user friendly.  My main complaints are its awkward way of adjusting volume, its extremely slow rewind and forward speeds, and its tendency to advance to the next track every time you touch it.  Also, I watched a few movies on it, and its battery length is not long enough to get through 2 hours.  Probably best to use it while attached to speakers rather than wearing it.  That way you aren't as likely to touch it, advance it to the next track
