I'm getting a point and shoot digicam and i've narrowed it to the Canon SD600 (or should i get the 630?) and the Casio Ex-Z850. I like the sony cybershots for style, which is one of my top priorities, but they dont seem to garner as great reviews as the Canons. I'm trying to keep it under $400 and am not a photophile but want the best picture for the price. Also, i hate shutter lag. Any suggestions?
