I believe my Bally Monte Carlo was $200. Everything was there but it needed some serious tuning to get working. It was stored in a moist outbuilding so there was a healthy dose of rust inside the game. Cleaned up pretty nice and about a year later I've finally got it up and running. I probably overpaid but seems fun for the era... I've only had it working properly since Super Bowl weekend - I finished it instead of watching the game.
