I am also going to say "Plasma".
I bought a Panasonic TH-42PZ77U Back In 2007...... And after three years of use, so far I haven't been disappointed......
If you are a Movie Buff or a Sports Connoisseur, Plasma is the ONLY way to go
Panasonic and Pioneer are the class when it comes to Plasma TV. Pioneer is on the way out from what I understand. So, if you want a Pioneer Kuro, or a Pioneer Elite Kuro, you better get yours now before it's too late. Because after Pioneer ceases their Plasma TV Operation, the only brands that will be left after that will be Panasonic, LG and Samsung.
Good Luck and Happy Shopping....
