Having a quick read through the AVForums threads, it looks like there a three in this price range, maybe have a scour over there.
The others they compare to the Sammy are the Tosh 42X3030 and the Sharp LC42-XD1e, all between £850 and £890 it seemsbut I sure a little digging could make those cheaper :wink:
I have experience of the smaller 720p Toshs and they great but no idea on the Sharp.
