I don't hype auctions too often, but I'm sure the arcade collectors out there know how rare this one is. It's not mine, but is being auctioned by a friend of mine, Chad. He's got top quality stuff and I personally vouch for him.
He has a nice SMASH TV up for auction as well right now (that I was thinking about buying, but figured I'd try my luck bidding as well )
