What's your budget?
That will be the deciding factor right there on what you should be looking at.
I'm using a Sony DSC-F717 right now; I was planning on bumping up to the F828, but Canon has a few high-end models that are stirring my interest...
Sony has really suprised me with their picture quality and the lenses they've been using (Zeiss on most of their higher-end units). I've had no complaints out of mine, except the same one I've had with digital stills for ages: few prosumer models have detachable lenses.
That's changing, though.
