I was in the same dilema a few weeks ago, took some advice from here and ended up going 42" LCD Panasonic, Freeview and HD. From John Lewis I got a free 5 year warranty too. It was about £650 - can't find it in stock now.
The picture quality is the best I've ever seen bar none. It arrived, I plugged it in, selected channels and sat down to watch TV :)
Then went out and bought a Panasonic combined Blu Ray/DVD/etc player for about £80.
Next a Panasonic home cinema kit :)
