Damn, Tim, That sucks a$$.
Same chit happened to me on a pinball machine bout two years ago in Phoenix Az.
Bastard said it was in "like new" condition.......... Filthy, inside and out.
Well, he discounted the pin and after about 20 hours of my time I have a badazz pin.
I didn't drive there to come home with a total project, but I saw potential in the machine.
Keep lookin' brotha. I know you , You'll get what you want.
