Dartmouth,
I'm also with you on this... definately decided on Panasonic but now they are about to release the LDZ800 in the LCD. Sounds pretty good esp with the 100Hz and 24p AND it's full 1080p.... (should be one better than the LDZ85) and I think they have put a better sound system in. Check that.
Yet to see a review on it but it's a choice between this and the PX80B plasma.
Money is not really a matter at these prices. Sure, give or take £300 but we're not talking thousands. I'd rather get a TV of choice than go for the plasma just because it's a bit cheaper.
Let me know how your decision goes.
I'm off to bother another, un-trained sales person in an electrical retail chain into putting various feeds on the tv's... hahah
FYI I looked at the LZD80 in store and I thought it looked pretty good particularly on non HD channels.
