I am looking to spend £1-2K on my television. I'm just looking for some responses from other 3D TV users at the moment to get some more perspective on things. I don't know about all of your requirements but yes, I am also looking at quality 3D, good built in sound, and excellent response times (for competitive gaming!)
I found the Samsung UE46D8000 sits nicely within my budget and meets the majority of my requirements, but I am concerned about the 30ms+ response times (for gaming). I see bfore has advised against samsung but I would disagree personally. I have bought many samsung displays in the past and the one thing you can be sure of is good quality/performance for what you pay. I decided to go cheap with my previous tv, a toshiba 42" LED edge lit display and it leaves a lot to be desired in terms of performance. It does a few things very nicely, but compromises bigtime on sound, grey tones, viewing angles, bezel quality. All the things you'd get with a brand like Samsung or Sony.
