While I understand there are plenty of folks who will overpay when they really want a chip set or part of a chip set, the chances of this actually selling at this price are next to none. The *only* person that buys this set at that price is someone with (A) little to no knowledge of what the chips are and/or (B) someone with a lot more money than brains.
Don't get me wrong, I'd love to see this set sell for $1200. As someone who owns ~2000 of these chips and is (more or less) done building/tweaking my set, that would mean my set just doubled to tripled in value
