This weekend, I'm replacing my F38310. Sort of. It's still working flawlessly and I've got a spare low voltage power supply module on hand if that ever goes but the big beast is headed to the downstairs rec room and getting replaced by a Panasonic 46PZ80U for the following reasons: The price just dropped to 999.99 at BB; I want bluray; I want the flexibility of moving an eighty-pound set from living room to family room with relative ease two or three times per year and...hmmm...I've got a grand burning a hole in my credit card.
A good to great plasma set is the only suitable replacement for an F38310 in my opinion. Pioneer would be my choice if money were no object but it is. a Panasonic, the 46" model, is sized, priced and configured just right for me. I've determined that the red/green push identified as a problem with the PZ line is more fiction than fact. Any reflection or excessive light problems can be minimized, in my situation, by one pair of curtains. LCD, although I am impressed by the Samsung LN46A650, was never a contender. The blacks aren't black enough, the whites are too white and that 120mhz motion control presents an annoyance;not a positive attribute.
Go plasma...for black level performance and color fidelity...for sports and other fast action programming. Also go 1080P...for bluray capability...and clearer text and graphics display at any resolution. But, hey, It's your money and your call.
