I'll be the first to admit I never overvalue a TAF because I think it's just an average game at best, albeit with a very good theme.
That PF is has issues. Planking, right inlane wear, and I'll guess under the electric chair cliffy isn't pretty. Perhaps flipper button cab wear too? Poor targets, broken plastics, and in desperate need of a shop job.
I personally wouldn't value it over $4500, but know there are TAF lovers out there that would say $5K all day. I'm not one of those people and would suggest you start at $4K and not go a penny higher until you can see it and play it. Your AFMrSE is probably in tip top shape and this isn't, which should be considered as a variable and unknown that works against his value until seen.
