I got my wife a newer one for Christmas, so I guess I should do something with the old one...
5GB iPod (model M5841), comes with original earbuds, charger, firewire cable, and box. I'll also throw in a Griffin iTrip FM transmitter, so you can use it in your car without cables.
This is the first model, which connects via Firewire.
I'm pretty sure that this is Mac-only, and will not connect to a Windows PC.
Edit: With a little advanced geekery, it looks like you can use one of these with Windows if you have a firewire port on your PC. More info here
The headphone jack is cracked, but this does not affect functionality. Battery holds a charge just fine. Front and back bear scuffs from normal use, but nothing severe.
$125 shipped, USPS money order only. First IM takes it.
