In my opinion if you are going to drop big bucks on a nice TV I would suggest Samsung, LG and Sony as the brands to look at with Samsung leading the way. Refresh rate it one thing that has become a huge stat recently. To me I can absolutely tell the difference between 60 hz and 120hz, but 120 - 240hz not as much. Additionally contrast ratio is something to look at, but only when comparing TV's by the same manufacturer. There is no universal method for measuring this, so a 4000:1 contrast ratio for Manufacturer x as opposed to 1000:1 for Manufacturer Y might not mean that much. Lastly is aspect ratio: 720 vs. 1080. Go for 1080p. There is a noticeable difference and I wouldn't get anything other than 1080. Generally these are what will differ when you are looking at between different models. Higher end models will have a higher refresh rate and contrast ratio. Additionally the more expensive TV's are starting to have network connectivity, apps and 3d ready functionality. The other matter is LCD, LCD-LED or Plasma. Plasma gives you a more "natural" feel, while the newer LED's give you more of that eye-popping almost 3d feel. At least that is my opinion. I am going to be taking he Black Friday plunge as well and try to get my hands on a 46" Samsung 6300 series from Best Buy. I would suggest giving them the eye test. Head to Best Buy and spend some time just looking at the differences between tv's brands and the specs. I would give specific attention to the refresh rate and Plasma vs. LCD-LED. Let me know if you have any other questions. I'm not an expert by any means, but I can try my best. EDIT: Colby beat me to it. But I agree with pretty much everything he said. Definitely at least 120 hz. I personally feel there is a difference between 240 and 120, but not a huge one and I cant justify the expense to go from 120 to 240 for the performance gain that I see with my eyes (all that really matters).
