I'm looking for a 46-47" LED LCD for under $1000. My main concern is getting the best black level I can find for that price range. Other features are nice to have, 3D, smart TV, etc. but secondary to picture quality and black level. I've been looking at the LG 47LM7600, Sony 46HX750, Samsung ES6100, EH6000, EH5300, etc. Any advice is appreciated.
