I found a Best Buy that carries the KDL-46HX850, amongst other models, including plasma displays. So I did some comparing and auditioned the HX850.
Honestly, I really felt the plasma displays were too limited in brightness for my taste, not to mention there are not too many available in a 46" size.
I demoed the HX850 watching Star Trek (2009). I was sold on that model as far as picture quality goes. They also had a HX929 there, but I noticed the screen uniformity issues that some reviews have mentioned. From what I have read, the HX909 is a bit better as far as uniformity goes, so I wonder if the picture quality would be similar to the HX850?
The price tag is also part of my final decision, and the HX909 is still available used for $1150 with shipping (with a $140 optional warranty), but the HX850 is $1688 new with a manufacturer warranty.
Which would you go for?
