If I do this, I will have it calibrated without hesitation. Yes, the viewing angle is perhaps my biggest concern. Light and reflection and such won't be a problem as I black out the room anyway. The 910 is not an option because of the room size. It's pretty big and the 910 would look very small.
At this point, if they called tomorrow, I'd have to go with the 57 based on what I've seen, heard from you guys, and most of all, my bad experiences with sony's tubes. I'm really hoping that any perceived PQ loss would be made up for with the much bigger screen size. DVD and HD are my only concerns. I will watch a lot of SD, but as long as the HD and DVD stuff looks killer, I don't care how well the set does SD. At any rate, thanks for the help guys. If you want to add anything feel free, I'll read it, and apply it to what I've already learned. Have a good one,
