If you are planning to spend that amount, I would wait a few months for newer technological models to be announced at IBC 2013/NBC 2014 and shake up the market.
If you're spending that much, Don't get an LCD or plasma, they are yesterday's news and don't clearly represent absolute blacks or absolute whites. As such the whole colour spectrum is not accurate. There will be affordable 2K OLED televisions out within 12-18 months meaning LED will be the norm and thus cheaper for the average consumer. 2K will probably replace 3D within that time too. I think you'll get a lot more quality for your money if you look at Panasonic/Sony offerings in a few months.
