Rich I have a Panasonic Viera TX-P42G20 (plasma) which is a slightly older version. The picture is stunning, the tv has been faultless for the 24 months or so that I've had it.
It has USB recording, which is a great facility, I can record in either Freeview HD or Freesat HD or normal SD quality on to a hard disk and the quality of the stuff when you watch is is as good as live. The only downside is that you have to watch the channel your recording or 'tape' two channels at once, because it doesn't have twin tuners. Nevertheless, with this model I can switch between the freeview & freesat facility and watch other stuff
Panasonic plasma gets my vote & money, got mine from John Lewis with a 5 year guarantee, but have a look at these guys
