The current latest models are the TZ6 and TZ7.
The differences between the two?
TZ6 has 2.7" 230k LCD screen and DVD quality (848 x 480) video
TZ7 has 3" 460k LCD screen and HD (1280 x 720) video
They also have slightly different CCDs (sensors) as, although the quoted number of pixels is identical, the TZ7's slightly larger sensor actually has a few more which are used by 16:9 video whereas the TZ6 crops the 4:3 image to get 16:9.
Otherwise, they are identical.
Amazon has both, TZ6 at £178 and the TZ7 at £237.20.
I'd go for the TZ6 every time as if I wanted a video recorder that much I'd get a camcorder and, heck, DVD quality isn't to be sniffed at.
£178 for the TZ6 is very good indeed - here it is
