I was actually at the last one too. I helped my buddy build a two player desktop controller and we bought the parts after the auction.
It was kinda funny.... I was looking at some of the more beat up cabinets wondering if they'd go for a deal. I saw one... was it a SF2? I forget exactly, but it had MASSIVE cigarette burns on the buttons, the plexiglass overlay had blue paint on it that was half chipped off... it looked hideous! I thought for sure it would go relatively cheap... it went for $1200 bucks!! Man, was I wrong! heh I was thinking like someone that wants to put it in their home, not like an operator. It had a popular game in it and it would make money. They don't care what it looks like!

I missed some of the prices.. I think that Space Invaders went for 400 bucks or so.. I would have like to see what that Hit the Ice cabinet with the board problems went for.. my friend loved that game it woulda made a good cabinet for him.

Hmmm, what about that carbon fibre sticker stuff? That's close to that metal look... I've seen that stuff in Canadian Tire before. (not sure how durable it is but if you powder coated the control panel first you could always peel it if it wasnt durable...)
