My eye is currently on the 42LG6000. It's a 42" panel, with 10-bit colour rather than 8, full 100Hz rather than 50, and it's got shed-loads of connectors round the back. It is, of course, full 1080p HD.
(I was looking at the 42LG5000, which was somewhat cheaper, but has now been made end-of-line. It's also good, but not quite as good.)
Anybody particularly enthused about something else in that general region?
ETA: My goodness, there's not a lot of info about this model out there yet. This post is already on page 3 of a Google for 42LG6000 + review.
