So I asked him for $280 back, because a "junk" TAM recently sold on eBay for $150. I told him that this is basically junk now, as it's only value to me was as a display piece. He agreed to $280.
I looked up Fedex from Chicago to Reno, and it appears, based on a 20x20x20 inch box (like it shipped in), it really was about $65 to ship to me. That wasn't the shipping method specified in the auction.
