People were speculating about what OP had into the game. He gave a detailed response and included shipping in his cost of acquisition which makes perfect sense, since it's also money he spent to get the machine. None of that means much in evaluating his asking price. If he got his TNA for $1,000 and was selling for $5,000 would the sale stall because he was obtaining an "unseemly" profit? Or if he'd spent $10,000 and was trying to sell it for $9,000 would he attract a sympathy buyer to cover some of his loss? Of course not. Supply and demand dictates the sale price, always.
So it doesn't matter what OP paid for it (except to him), only what a HUO TNA that's ready to be delivered today is worth right now. And as for the hand-wringing about whether he should "include" his shipping costs when pricing his game (vs. looking at comp. sales or using an Ouija Board to pick a price), Tommy Lee Jones said it best:
