Absolutely no refund? eBay can screw that seller hard. Buy it for 100k, when it arrives report a defect that wasn't described correctly or accurately. "There's a little scratch on the game connector, it is not mint or near mint as claimed"
If he tries to fight back on not as described claim, he will lose under eBay rule. The only question is who has $100k to waste and is big enough a dick head to try and make a return for refund on his no-refund rule.
