Negotiated hard on a Silverball Mania in really nice condition. Ended up getting it for $400. But here's the best part of the deal.....
Seller agreed to give me Silverball Mania for the $400 but only if I took a pretty beat up Williams Winner with it, just to get it out of his house. Big, heavy machine if you've never seen it.
Managed to get it home...A little elbow grease, the Winner cleaned up great (plexigalss playfield took little work). Played great. Sold the Winner in a couple for weeks for $500, which was actually kind of a steal for the new buyer given the shape I left it in.
So bottom line: "Buying" Silverball Mania" netted me $100 on the positive.
