Yeah, that's typical for a retailer to overprice a game that much. Pinheads are not their typical market. They'll probably sit on the SST for 4 months until a guy with a big bonus check and a space next to his pool table walks in and makes an impulse purchase.
The thing that sucks is the same guy will decide to sell it six months later and then find out he can't get half what he paid for it.
