I actually picked one up that was thrown in as part of another ebay buy. I originally planned on fixing it up but it turned out to be a bigger pain in the ass so I binned it. I guess if it's in proper working order you could keep it or sell it on ebay although I don't think they'd be worth that much. It was about that time Apple started on their downhill decent.
It's probably the reason people took to them with sledge hammers, because they were just shit. Niggly little problems and to get the thing apart (without loosing any of the screws or breaking something) took half a day.
