Its the TC-P46S1. I swear these panny plasmas get better with each panel generation. This is the third year in a row I have gotten a new one (sell the two year old, buy a new at little to no money, keep two at a time), and each one was the best I have had until that point.
This one, I still have not gotten dialed in exactly how I want it, waiting for the break in period to end, but I can already see the promise that is there. Some of it is screen size, some of it is simply improvements in the panel itself. All in all, so far I am VERY impressed.
This may be the one I get professionaly calibrated since I saved so much money on buying it after selling the last one.
