Woohoo! I've been looking to buy a Spirit of '76 pinball for a while now. When I asked about it in the Buy/Sell forum, I learned that it's considered a bit of a collector's item anymore and that it was pretty spendy.
Well, I just found one. $700 and it's in fantastic shape. Owner had it serviced about 8 months ago through a local company. Called them and reviewed the service record and it was in good enough shape that they tried to buy it off the owner, who refused at the time. I'm probably picking it up later this week. So excited!
The reason I want this particular pin so bad is because my father in law was one of the engineers who created the machine. He apparently designed the sound system. I just think this will make an awesome family heirloom.
