I agree with Steve S, and here are a few more thoughts. CES is in January but the new models won't hit the stores until late March or after. I can't recall any great sales on older models when new ones arrive and I'm not sure the Superbowl leads to great deals on name brand models. Right now there are a bunch of 50-55" name brand models between $999 and $1300. I would avoid plasma, especially in a well lit room. 3D and WiFi each will add $100. You'll need a wireless router for WiFi to work. In LED models, you'll pay $100 more for the thinner, "slim" models.
The most important requirement for an LED is 120Hz. It allows for a smooth motion feature to provide some control for motion blur which may or may not bother you. If you get a 3D set, that spec should be upped to 240Hz if the set uses active shutter glasses. Other, higher, refresh rates publicized are marketing creations that attempt to combine other features.... just stick to 120Hz or 240Hz for 3D/active shutter.
Picture quality can diminish when sitting off to the side of LED sets. Go to Best Buy and look at various brands. LG is supposed to have the best viewing angle, but I feel most brands hold up well when viewed from the side.
Top tier brands are Samsung, LG, and Sony, with about 30, 12, and 9 % of the market share. You can't go wrong with them. To get an immediate snapshot of sets available, go to the Best Buy website/ Products/TV and Home Theater/ TV Finder. Enter price range 900 -1300, Screen size 50-55", Brand Samsung, Technology LED, select Display Results, and it will return ten Samsung sets in your price range. The EH models are slightly thicker and the ES models are "slim" models, and higher in price. http://www.bestbuy.com/
Switch to LG and find four sets. There are no 240Hz sets because LG uses passive 3D glasses. Check both LG and Samsung to compare. 14 top tier models to choose from between $999=$1300, not bad.
