I have been told in another High Defenition forum that the PQ of the Panasonic TH-42PZ800U is far superior to that of the TH-42PZ80U, and that is worh spending the extra cash! my parents have the TH-42PZ80U and it looks darn good, the 800U PQ is even better? I'm getting a Panasonic for myself and I can't decide, because I have not seen the 800U in action , only the 80U! Do you guys think the 800U is worth the extra cash??
