... "You will not find this chip for sale at other auctions."

Well, it was in another auction, through a different seller, less than a week ago: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=6164205530&rd=1&sspagename=STRK%3AMEWA%3AIT&rd=1

That one went for $512. I can't imagine it going for anywhere near there from now on.
