The Canon SD1000 was the replacement for the SD600.
There is now a SD1100IS which is a SD1000 with Image Stabilization.
The only reason to buy the SD600 would be if you could buy it for much less than the SD1000.
I've been doing some research and I've found numerous favorable reviews concerning these two cameras based on performance & image quality. Does anyone have personal experiences with either of them? I know the SD600 is discontinued, but I'm willing to put out a little more if it's definitely worth the money.
Thanks in advance for the help.
