Ok, here are the 3 choices: Panasonic pt47wx49 Samsung HCL4715W Sony KP-51HW40 I've narrowed it down to one of these 3 and I really need some opinions. Either for or against these particular models. The set will be used primarily for watching DVD's currently. If it makes a difference, I do plan to get the set ISF calibrated. I've read alot about how the panasonic looks simply awesome once calibrated but I'm concerned about the "pop" problem I've heard about these sets. The samsung picture looks great but there doesnt seem to be alot of info on these sets. The Sony looks really nice and is a slightly bigger picture but for my viewing distance, 51" is the max I'd want to go. Is the Sony worth the extra money (probably be about $700 or so more than the other 2 sets.
