Get the G6
I had the S70 and returned it. Not for defectiveness but b/c it has large shaded corners on all four sides when using flash inside against a wall for instance 6-10 feet out. This is called vignetting and the S70 has LOTS of it unfortunately.
It also has purple fringing that's higher than average.
These defects are errors too large to ignore--especially for a $600 camera. These defects also has been noted in pro camera reviews like this
one.
I havent't compared directly against the G6, but other people in camera forums have, and all are in general agreement that the picture quality of the G6 is substantially better--no surprise as it has a better lens.
If you're going to spend that kind of money for a G6, you should also consider a much superior camera when the
Minolta A200 comes out soon. The picture quality is supposed to be superior than the vaunted A2--a true prosumer camera........Besides better pic quality (better glass/latest sensor & improved imaging system) of the A2/A200 over the G6, the A200 has manual lens focus and a wide 28mm lens (like the S70), but a long telezoom of 200mm! Plus video abilities of the A200 are
MUCH superior to the G6 at 800x600--the only camera in the industry to do this at this point......Oh, and you can't forget the Anti-Shake. This A200 is a TRUE enthusiast cam....and will assuredly be better than the A2 b/c of the latest tweaks.
If you absolutely can't wait and need something NOW, then get the
Pentax Optio 750z.. It's been rated by enthusiasts higher in direct comparos with the G6. Its smaller size, better video quality, and substantial lower price also gives it brownie points.
Yes, the G6 is a good camera, but with the price points you're looking at, any enthusiast "in-the-know" and who has done their research (like me

) will steer you to the Minolta A200/A2 or Pentax 750z.
Go
HERE FOR RESEARCH.. But I've done months of it for you

as I'm also in the market and waiting for the A200 myself.
When ready to buy something, price-match the lowest CERTIFIED internet dealer price to
Onecall.com. They are a CLASS outfit that also will give you a very good price. They are very well respected in camera circles.
Good luck!
