My local gym sold it for 400 quid. Not exactly cheap, but it came with the cabinet, and I'm sure it was originally much more expensive. Come to think about it, I dunno why I bought it really, must be nostalgia (it was originally only available at the arcades in the mid-'90s, and there were no ports), 'cause I'm sure it must be available on Mame.
The hardware itself is prety ancient, it's running on Intel's 386 IIRC.
