I'm looking to buy a new LED TV for about $2k. I had just looked at Samsung's 7150 I believe is the model number. Has 3d, micro dimming, looks to have nice blacks, and nice colors to it. I like the 240hz motion it has. Is this the best candidate for what I'm looking for? Or do I need to check out Sonys 950 series? Or should I be looking at something else? Is it worth looking at the 4K models right now? I need professional help on this matter please....
