about as much as the boat it rode in on...
Just kidding but seriously I purchased one last year for a crazy 1300 dollar price and it was in need of shop job and coils needing replaced, I had just got into the hobby and was quick to make a purchase.
I think a really nice one near perfect would sell for 1200 to 1400 in great shape, but if its faded and worn playfield and needs work I would say 700 to 900 tops.
