By default, any 240hz TV, like the 8500 Samsung you are looking at, is 3D, so if you don't want 3D, skip that one. That Samsung is also a 240Hz TV, which I personally do not like. To me, a 120Hz TV is great without the weird processing artifacts that 240Hz creates for film-based content. If you want Star Wars to look like it was shot on a cheap home video camera, then 240Hz is for you.
Other than that, the "best" TV for you is the one that looks best to your eyes. Plasma get very high marks for looking the best and having the best motion and black levels. LED gets high marks for being the brightest and pumping colors to almost being oversaturated. LCD gets high marks for being good at everything but not being the best at most. Stay with brands like Sony, Samsung, Panasonic and you will be good.
Okay, here goes. I am in-the-market for a 46" HDTV and have hit a brick wall. I guess it is paralysis by analysis. I am not ready to jump on the 3D craze quite yet. I am looking for the highest quality picture and sound for no more than say $2,000. I am leaning towards LED models but am open to all suggestions. Most recently I have focused on the 2010 Samsung UN46C6800 and 2009 UN46B8500 models, but the problem is I cannot find any reviews or customer feedback on the 2010 model. Any suggestions? Appreciate your time and help!
