I'm still rocking the PZ80, fantastic set. My in laws have a new £1500 panny lcd and whilst its nice and bright, mine has a better picture still and its 6 years old!
I'm waiting for a 50inch oled that's around 1k before i even consider upgrading.
£1k OLED will be a long way off at 50" I fear. There aren't many better TVs to be stuck with than the PZ80 though! I Practically gave away my PZ80 back in 2011. It was (and probably still is) a brilliant set... almost worth keeping as a spare!
