Cant beat 1080p panasonic viera for the price in my opinion. I bought the aquos 50inch 1080p as it was extremely cheap and i have nothing but good things to say about but if i had my time again id probably raise the extra cash and go with a viera.
think it might be tough to get 1080p for £800
Viera in a 50 inch is about 2 grand without the stand.
