I would recommend LG as first choice or Panasonic second. Whichever you get however consider getting some good external speakers, most flat screen TVs have abysmal sound, older TVs with tubes at least had a reasonable size cabinet giving slightly better acoustics.
It's not necessary to go to the lengths of multi speaker "surround sound/home cinema" installations unless you enjoy that sort of assault on the ears, good stereo is adequate for normal people, surround sound is just a ploy by speaker manufacturers to sell more speakers, complete overkill in my view.
If you listen to music in a concert hall, it comes from in front of you (unless you're performing) so surround sound is not natural for music in my opinion. It maybe OK if you enjoy big action movies but not for music or "theatre"" type productions, not a lot of point in it either for news or most documentaries.
