you didn't mention 3d did you?
i wouldn't worry about 3d tv's yeT
anyway i bought an Lg at xmas and it is superb,i know that it is the cheaper of the best brands and it was all i could afford,but i can't complain and according to the manual i get a 3 year on site fix/swap so that 's me happy for a few years,
i can't imagine any modern telly not coming with a built in digi box these days unless it's a specific model tv,
i suggest you buy the best that you can afford,i don't think you will be dissapointed,i wasn't,and its brilliant for games and movies,i did get a full HD model,which is what i wanted
