Eye fell on the ixus 500/510 hs bcoz i know the ixus series are wonderfull.

http://snapsort.com/cameras/Panasonic/TZ20

http://snapsort.com/cameras/Sony/HX9v

both being a little more heavy but maybe also options.
Can anyone give some additional advice?

ps: i know the basics and some advanced stuff bout camera's , so i don't look for ' you dont only have to look for Megapixels' . I know this:P it's just ,more advice , maybe expierence :)
