make sure you sell it to someone who wants the game and not a cabinet.. otherwise it'll get mame'ed or at least converted anyway.
Too true - I know a guy that was looking for a dedicated Time Pilot. Finally, one showed up on eBay not too far from him to pick up. This guy and the seller actually knew each other thru forums, but didn't know each others eBay handles.
So this guy bid, and ultimately lost, the eBay bid.
The guy that did win went to pick it up, and the seller was going thru showing the insides of the cab, and the guy stopped him. Said he didn't care about the insides at all as he was going to put a 48 in 1 in there anyway and drop the insides on eBay.

It was only after the fact that the two mentioned above became aware of each other when the seller was griping about the guy parting the cab, and the other guy was like "oh crap, that was you?!?!"
