My problem with eBay is the whole sight unseen factor. Once I saw a listing for two JD's and two Dr. Who machines from a guy near me. I sent him a mail to call me, if he minded if I came by to take a look before placing a bid. He had 4 of each game, and was just trying to part them to get one of each working, and selling the other's to get cash to replace the MPU and power driver boards that were missing from every game.
Based off the pics online, this would have been a disaster. You really could not see how much damage had been done to these pins. Rottendog replacements looked around $450 for the two boards just to get the game to boot, and who knows what you'd have been in for then. I threw a number at him for the two Dr. Who's, but said you're already getting more on eBay, so go for it.
I imagine the winning bids would also have to pay to have them shipped, and I bet they weren't happy unless they were just looking for several parts that hopefully would still work.
I'm so glad I went by there.
