2 cents worth.
I've had arguments about selling things for more money then my competition. I add the benefit of knowledge and support and better quality. Some feel your unfair and greedy. Especially when I resold a laser for huge profit over what I paid and after some investment of refurb and warranty.

So I posted this question. If I won a Lamborghini, and decided to sell it, what should the price be? If based on what I got it for it'd be less then nothing if everything goes down in value. If not,then how much?
I say fair market. That's whatever you sell it for to whomever will pay, even if 1 guy steps up and finds its a fair value. Feelings don't belong in business. The hobby is owning and playing. Once you sell, it's business.
I find I too get jealous I can't justify 10k for a game and someone else does. Some on the outside looking in might think we're all idiots spending 500 or 1000 on a game.

Also, just because the manufacturer sets a minimum price to avoid plummeting of the collector market, and for pure profit to keep prices high on newer games, doesn't mean that a retailer, private seller, or anyone can't sell for whatever they want. Call it what you want. This isn't like scalpers buying up concert tickets for the purpose of scalping. He bought 1 game. Concert scalpers real tickets for 10 times or more than their value. This guy's asking a hair more because we all know everyone of us will offer way less, even if he stated price is firm.
