Seller should not be ripping off pinside. I might blast the place but rules are rules and if you are on here you follow them.
Buyer got what he deserved. Bought sight unseen. Game was transported 6 hours. Then he sat on it for 6 weeks. I have 0 sympathy. Suck it up and consider it a lesson learned.
I know a lot of sellers, myself included, who tell buyers that they guarantee the machine works until they move it. I've moved machines to shows that were hours away and even tournaments which were 30 minutes away and watched them melt down the instant they were turned on.
