Can't say. I have only seen one cabinet in 10 years of collecting. It wasn't for sale. 2 Player cabs are a little more common and are usually a conversion. Seen a couple of those. I'd guess a complete 3 player cabinet would go for $650-1000 depending on condition. Very fun and scarce game.
All others welcome to jump in and price a cab. I am only going off experience. There is a game price sheet somewhere out there. (Which I don't use that might be of some help)
