Yeah, there was a Superauctions auction at the State Fairgrounds in Detroit last week. I spent about an hour there and then went to Autorama to see the 1966 TV Batmobile
Most of the cabinets were in really rough shape and I saw at least a dozen go for less than $100. I always go to these in case there's something nice like a TRON cab. There was an Austin Powers pinball machine, but I didn't stay long enough to see how much it sold for.
