Quoted from dkeruza:Would you buy it back for $400 shipped?
Just keeps seeming more and more like buyer's remorse. You've hardly come close to being scammed, you set the price, you said yourself you knew beforehand that it would need work, then you did the math and realized you over-paid, then blasted the seller publicly. He graciously provides a partial refund, which was the right thing to do so neither one of you gets screwed, and now you publicly try to negotiate a sell-back, which would cause him to lose money on the deal.
You're a piece of work.
