Wow! My quest is over. I just purchased the 46 inch UN46F6400 and I must honestly say that I do not regret my purchase one bit. Ok, I wish I could have afforded to buy a larger screen, but I'm still very happy with the 46 inch. I researched 3d HDTVs for months after getting a demonstration from a friend of the TV's capabilities. He purchased a similar Samsung 3D HDTV and blew me away with what I saw. I was stunned by the picture quality and equally stunned at the quality of the 3D. Years ago I had seen a demostration of a 3D rear projection HDTV and I wasn't impressed by the quality of the 3D. Boy, times have sure changed. My research of 3D HDTVs included all of the major popular brands and I even watched all of the CNET reviews online for all of the HDTVs. The 3D quality of this HDTV is STUNNING! I mean it! STUNNING! On numerous occasions I caught myself ducking to avoid 3D objects hurtling my way from the screen! Stunning picture quality and stunning 3D. Well worth the purchase! When paired with a Samsung 3D Blu Ray player be prepared to see some stunning HD picture quality! Please note that the 2d-3d converson is so-so, but hey, its not real 3D. Look, if you want to watch 3D then watch it in 3D. 2d-3d is basically a gimmick. The Smart TV apps are great but I will be purchasing a wireless keyboard because on screen keyboard is a hassle to use with the remote.
