Backglass and playfield look fantastic for the age of the game. Would suggest contact applied to the playfield. Cabinet is poor and out of the three major points of a good quality game (Playfield, cabinet and backglass), you have the easiest component to replace / repaint.

Board issues - will need an Altek and repining of most connectors to ensure reliability.

Price - Ask how much they want, and if they reply with the usual "Ebay has them for $5000", then I'd go there with $1500 in my wallet, and a spare $500 in the back pocket. Slap $1500 on the machine.

I'd pay $1500. Lowball won't work on Playboy, KISS etc etc..
