I agree with the others I would go for Panasonic and definitely plasma, ideally with at least 2 x hdmi sockets and it is very useful to have a usb (I download movies onto my data stick and playback thru tv) network enabled is another door feature, especially for updates etc.
Personally I am avoiding 3D as I cannot imagine me siting and watching a movie with a silly pair of 3D glasses on, I also believe it is just another fad, like it was the first time around.
