Well got mine last night and got it up and running. Happy to report, it appears that I have no bowing issues. The picture is great, especially with not having all that much time to tweak it. I just went with those basic settings from another thread and it seems to be really nice. The set looks better in person. I was afraid of taking step back in PQ from my 57" Hitachi, but I glad to report this thing looks great. I am running Dish network HD and a samsung up converting DVD player. Sound quality sucks, but I never use the TV speakers anyway as every source I have goes right to my Yamaha.
So for you guys on the fence about this TV (like I was), here is a vote that says it looks great.
Also, is it possible I got one thats fixed already? The guy at CC said they just got these in and only had two.
