I can't believe it, a simple search on ebay turned up a bunch of them at $13.51/copy, 1066 mhz instead of 800 mhz but should work. I bought 4 for insurance. Be here Monday. I hope they are good, claimed to be brand new. Not only that, there seems to be a plentiful supply of D525MW motherboards, lots of used ones, and quite a few that claim to be new. So all is not lost on one of the best lcnc motherboards ever. Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
