Since coming over from my Pioneer PDP5070 I am really enjoying the LCD panels. I recently bought a Sammy 630 and noticed that the 750 is on sale for couple hundred dollars more. I am very pleased with the 630 with SD and HD and Bluray looks amazing. Only question is the 750 really that much better and I should def upgrade to the 7 Series? My family room is kinda bright but is there a huge difference with reflections? Have 2 big windows at the side but if PQ of the 750 is much better and has many more features i should return the 630 for the 750? Would like to know what others say. Thanks guys.
