That really stinks, but is not too surprising, given the number of greedy BIN Sellers overtaking ebay these days. I hope you and he can somehow work a resonable compromise.
Unfortunately, you may have to wait it out... until after he experiences a few weeks with no nibbles at that goofy price. Best of luck either way...
Also I am assuming you already have the Tommy Bridges Pinball Game? Only reason I bring it up is that a nice example was at the National, and I couldn't help but marvel at it. Good seller, too. Being an advanced Bridges collector, I would bet you already have it. Just wanted to make you aware
