The 650 is a nice HDTV, but I personally dont like the grain in the picture when viewed up close. And my honest opinion, toshiba is the way to go. They have a game mode that corrects input lag, no other large screen has this and even though toshiba, says there lcd's are 8ms refresh rate studies show they are closer to 4ms.
And with SRT technology there picture on SD, programs are the best of any lcd, including samsung and sony. I like sony alot but there over priced samsung's are nice to but I think there over priced as well. Toshiba offers there TV's for hundreds less and if you look into there TV's you will see there just as powerful as sony and samsung, and in many ways there TV's are superior in processor power 14bit mostly, add in deep black's, vibrant colors. Toshiba is the best priced high quality lcd maker period.
