Rat, I am a huge fan of the Panasonic Lumix range. I recently got the FZ28 with a x18 zoom and its ace, even the HD video, it better than my 3CCD Camcorder.

The only downside I see about the G2 is that you will have to buy extra lens's - However this maybe what you want to do.
Anyway you will not go wrong with a lumix camera.
