I got my PZ85B for £1030 and I know the PZ80 is a good £200 cheaper than that so you could probably get the PZ80 for ~£800 (google TH42PZ80).But the new PZ80 panasonic should be a very nice tv as well, but then up at that pricelevel it's best to spend another few 100 on the 508XD pioneer which really is the best value tv out there with its astonishing PQ!!!
"a few 100" in this case is actually twice the price.
