I purchased a full HD LCD TV last november, and my suggestion would be to go for the LED TV. The picture quality is just so much better. The viewing angles, the contrast, are all better on the LED, and it is sleeker.
My budget was limited and I wanted an internet TV so I went for the LCD, but believe me LED TV's are far better, and as for the internet functionality on these TV's, it is not so good as it may seem.
