if you're speaking of the nickel roll down game then I think mr bally is pretty low in his price range. On the rare occasion that I see these for sale it seems like they're always in the $1000+ range. Granted, that's what they're asking for them, but I'm guessing they're getting close to that. You don't see them very often.
Full disclosure, I own one of these, but I'm not price pumping. I paid more than mr. Bally's highest range and mine didn't work when I got it.
If you could get it for a couple hundred I think that'd be a great deal.
