I have got the lumix tz7 and I find it very good. 10.1 mp, massive screen,25mm leica widescreen lens, 1080i Hd video (only15 mins at a time)
It's very easy to use even with my left hand (rh throttle) I covered mine in heavy duty velcro so it sticks to my reserve container or fits in my jacket pocket.
I tried taking a dslr up last flight but its a pain in the arse!! cant use the bloody thing with the left hand no live screen, cant zoom, too bulky for flying imho
Here are some images I have taken with it.
here is a vid it's an awful vid but gives you an idear of the quality

It's not the cheapest camera out there but you get what you pay for
If I was buying a camera for flying and general picture taking I would buy this one, but if I was buying solely for flying I would get the gopro hd.
