Refurbished Creative ZEN MP3 Player 2GB (Black)
This thing worked well for about 6 weeks.  Now it locks up and is unusable.  I'm past the return period, so I'm stuck with a piece of junk.  Creative Zen has a troubleshooting section online, which walked me through wiping all the data and reformatting the drive.  That worked...for a day.  Now it's frozen again.
