Best of luck with your needs, I understand how this can take awhile to choose.
You Pioneer s/b a great set! I'm reading article after article on how 720p can be in your favor, and the need for additional resolution will not be noticed. Plasma has some pluses that LCD does not.
I did not consider any of the other sets at Sams.
The off axis viewing on the Olevia does seem to fall off somewhat as you watch from left to right, no big deal for me.
The backlight of this set is the biggest issue, rearing its ugly head in dimly lit scenes, but mainly on poor transfers. The low level scenes are not that bad, especially with what you get for the money, 65" 1080p. If your are into dark, dim, poorly lit movie scenes and programing, choose carfully.
Just watching a good HD transfer on this set will spoil you! The 1080p over 720p in my room would make a difference, we do not even have a Bluray or HDDVD player as yet.
The Olevia came with a 1 yr, our $100 membership came with an addl. 1yr., and bought the third 1yr.
