Actually these ship from China... apparently via a *very slow* boat unless you pay oodles extra. They're undoubtedly being sold either by the OEM manufacturer themselves or via a gray market reseller that gets them "off the back of a truck".
On one hand it would be "interesting" to play with these and try to get one of the old LCDs out of the scrap heap working as a stand-alone monitor. (I have a really beautiful 10.1" 1280x768 one saved from an otherwise horrible Crusoe-based laptop.) But on the other, well... getting it "right" is probably something of a trick, what with having to purchase the correct cables/inverters/whatever, and by the time you've bought all the bits it's not going to be cheap. And of course if you break anything in the process (or likely, if the board you buy doesn't work at all) your only warranty is you're allowed to keep both pieces.
