MDS, Onecall.com has the 52LX177 for $3000 with free shipping. Just thought I'd let you know. They've got a good reputation, and it could save you some coin.
EDIT: Also, if you're not set on the Toshiba, Onecall.com has two other 52" LCDs on sale (Sharp and Samsung) this weekend. Just check out their weekend sale. In addition, in theory you could get the Onkyo 805 for $720 if you buy any of those TVs through Onecall because the 805 is on sale this weekend, and there is supposed to be 10% off audio equipment when you buy an HDTV. The 10% discount didn't ring up in my cart when I tried it, but they might honor it if you call.
