I think Black Friday is great if you don't want to order online. You MIGHT be able to get a better deal on Black Friday than you can online, but I can't say for sure. Some sites like slickdeals will have a Black Friday forum with a lot of leaked information from employees about what deals there will be and how many of each will be in the store.
Here's another set to consider:
JVC 47" for $1,900 shipped. A lot of good things have been said at avsforum about the JVCs, so it's probably a good set to consider. If I were personally getting a 46-47" LCD, the
Samsung 4671F, the
Sony 46XBR4, and the
Toshiba 46LX177 would be at the top of my list.
CNET just reviewed the Sony and said "Although not quite as impressive as the best plasmas, the 46-inch Sony KDL-46XBR4 outperforms any flat-panel LCD we've tested so far." They also review the
52" version of the Toshiba. The Samsung
4661F and
4665F have also received good scores from CNET. They are two good models to consider, and they fit better within your price range.
All three of those Samsungs have glossy screens, so don't get them if reflections would be a problem. I'm not sure about the screens on the other TVs.
One big question I have is if you will be doing any PC usage other than gaming. If not, then I would recommend looking into a 1080p plasma, specifically the Panasonics. They have great deals right now, and the only reason I wouldn't get them is if you'll do a lot of web surfing, text typing, etc. that might cause burn in. Even if you do those, if you have a 1-minute screen saver and hid the taskbar, then it could be a non-issue. According to
this thread at slickdeals, the 50PZ700U was (and might still be) $2,140 + tax at Sears B&M when you use your Sears card. This isn't the best plasma out there, but only the very best LCDs should be able to trump it in PQ, meaning you would have to spend about 50% on a 52" LCD to match the PQ that the Panasonic plasma will deliver. The Samsung 4671F and Sony 46XBR4 might be able to match the PQ, but they cost more than this TV and are smaller. The jump from 46" to 50" might not seem like much, but the screen size increases by 18% from 903.45 sq. in. to 1067.52 sq. in. (

Edit: Here's a
link to some more support for 1080p plasmas. In case you don't go there here's a quote:
Three distinct groups emerged from this test of the twenty 1080p displays. All displays in the top group were plasma HDTVs. They all had a static resolution of 1080 lines and a measured motion resolution of 830-880 lines, depending on the specific display. The next group consisted of microdisplay rear projectors, static measured 1050-1080 (depending on the display) while motion resolution ranged of 610-780 lines. The bottom group were all the LCD flat panels, with a static resolution of 400 (one panel) to 1080 lines and motion rez coming in at 360 lines (one set tested) to 600 lines. Three of the LCDs tested were 120 Hz models (one was the Sony KDL-46XBR4 reviewed here), all 120 Hz models had 600 lines of motion resolution.
