A few years ago I bought a tron power supply board off an ebay seller who said it was untested. At the same time he was selling a tested and working ps board for 5 times the amount. I bought the board assuming it didn't work. The photos were carefully done so as not to show the missing components and acid damage. Out of principle, I left negative feedback stating that this was not untested but clearly defective to anyone with half a brain. The sob left negative feedback in kind saying "what part of not tested don't you understand?". My reply, "The part where you knowingly commit fraud and pretend you are not aware of it." This is why Ebay no longer allows sellers to retaliate with negative feedback. Just don't do it. Don't be a douche. Be honest. It has always worked for me.
