I already have a few SLRs (digi and film), so the zoom isn't an issue. I just want good quality pictures at a snap. I've never owned a point and shoot before, used a copule a bit but didn't like them much, one was a Canon A5 something or other (no IS), the other a Kodak or sorts. Now I want a back up to my hefty cams, something I can take everywhere. Both the TZ3 and 850 IS come highly recommended, but I'm not sure. HELP! or if you have any other suggestions
