The Best Buy Black Friday sale on the 56HM66 at $1199 is not a "doorbuster", it's not limited to 5am to noon, in fact it's a 2-day sale, all day Friday and Saturday.
BUT, of course, it's limited to "while supplies last". In this case, warehouse supplies rather than store supplies ... the presumption being that you buy the set and pay for it, but pickup or delivery is "later" [the following week, after some sembalance of sanity returns]
I asked a guy at BB if he knew what they expected in terms of availability. He said that really they had no way of knowing ... they knew neither the level of demand, nor the exact quantity that would be available. But the warehouse supplies are relatively large (hundreds to over 1,000 units per warehouse), and it was his guess that these would not sell out within minutes of when the store opened, like the "door buster" items do. In fact, he thought that they might last through much or all of Friday.
I'm kind of torn ... Best Buy has had both the JVC 56" 1080p (which I think is a better set) and the Mitsubishi 57" 1080p (may or may not be a better set) on sale for $1999 already. And I won't be surprised if SOMETIME between Thanksgiving and Christmas, we don't see these and similar 1080p sets for $1,599 to $1,799.
The picture quality on the Toshiba is superb, excellent .... for 720p. But it's not 1080p, and I think that the JVC set has better picture quality even in their 720p models, I think it's a superior technology. [However, JVC has had lamp life issues that scare me to death.] Additionally, the connectivity of the Toshiba really is not that good ... it has both fewer and less versatile inputs than a number of other sets (no 15-pin VGA analog input, and the warnings about "can't use a PC with HDMI", although I think that with proper setup on the PC, that's BS and you can do it ... I THINK). So while $1,199 seems like a good price, I'm not sure that it won't be better to wait for a better deal on a 1080p set. [What I really want is a 1080p direct view LCD with a screen size in the mid 50"'s ... and BB has one, but it's $4,400]
