I have one I might be willing to sell. I would want to sell it with a few accessories though and for about $200-$230. It is in great shape. I would want to sell it with:
iPod headphones (x2)
wired remote
firewire calbe (of course)
car charger
iRock FM transmitter (for car without a tape player)
musicmatch jukebox license (for use with a PC)
Let me know if you are interested (or even better, if you have a used iBook 700 MHz dual USB logic board you might want to trade -- working of course).
