Choosing your first HDTV is a big event, so I would suggest that you take your time and make your own decision rather than being swayed by comments from others.
Listen to what others have to say, look at what is available in your price range and if possible go to a decent audio video outlet so that you can see your short listed TV's in action.
Also remember that the price you pay for a particular TV will differ by a few hundred pounds depending on where you buy it.
