Costco has the Samsung UN55EH6050 (UN55EH6000) @ $799 starting Thursday.
I think this is a pretty good deal, for a backlit (yes, with LEDs) "dumb" LCD TV. The 2 HDMI is kind of a bummer, but if the picture quality is a good as they say, I may bite. I'm a bit worried about the off-angle viewing, but maybe I read avsforums too much.
Note that this $799 price should include free shipping.
It looks like the Vizio M3D550KDE is back in stock (was OOS for a couple of days), also at $799 with free shipping (when ordered from costco.com):
