If you are looking to spend that amount of money on a new television please consider spending a little more and looking at something like THIS
With all due respect, I can't help but feel you would be wasting your money on the models you suggest. The Samsung i recommend has huge value for money, awesome reviews and a ton of features for the money. I'm sure you won't regret spending the little extra on it!
Thanks mate, not sure of the cost of the TV's i mentioned are in your part of the world but the PS51E550 is going for the equivelant of 769 pounds and the UA46ES6200 for 846 pounds where i'm from. The TV you recommended above is amazing but a bit out of my price range at the equivelant of 1900 pounds.
