I spent an excessive amount of time on AVS before I bought my TV and have seen all these points debated, redebated and then debated again. In the end, I used DVD essentials or something like that and am continually amazed at the jaw dropping clarity and color of my TV. I am glad I didn't drop the coin on a pro to come in and access my service menu to tweak color, temp and grayscale.
