for $600, i think the panasonic lumix FZ50 cant be beat. I also like the canon G10 but i think the FZ50 is better
been using the lumix for 2 years. amazing zoom 35-420mm equiv. NO serious need for other lenses, though i wish it went down to 28mm cant complain when it goes up to 420 mm

took this (w/ FZ50), probably 75 feet away, no flash, no tripod, low light...not bad because the zoom is great
