Skip,
I've sold several of that title in the last couple years. Without seeing the PF it's hard to gauge price. This was my last one, a previous buyer had me install a new CPR PF and a buddy redid the cabinet. I installed a new MPU and it sold fully working (before restoration) for $1400:

I put a CPR PF in it and again the cabinet was restored, post 137:

IMO with almost 20K produced, unless the BG is mint and the PF is near mint, a non working PB is a $800 game at best. I won't even post what I paid for the last one but I had a lot of work getting it running. Factor in the lack of game specific parts (apron decals, crap pop bumper targets and pop bumper caps from Classic Arcades, and $950 CPR PF's) it's hardly worth dropping big money in restoring one when there are many out there already restored for less then putting the $$$ in one.

Now if someone just wants a player condition game, that's different story. But I've bought them fully working for under 1K.

Just my .02 cents.
