...is to do a side by side comparison, with confidence that you are using the same source material under the similar lighting conditions to get a feel for what your eyes and not written specifications say.
Personally, I'd avoid the PZ80 series unless you were getting an incredible deal. The newest Pannys are getting generally favorable reviews by consumers as well. I see ABT has the newer Panny you list for $1597 with a rebate available if you purchase installation services.
