I have a Canon A620 and can attest that it's a quality piece. I'm hardly all that camera savvy, but I've certainly been able to impress people with some of the photos I've taken with it.
However, if you want to take pictures without a flash in dim lighting, it's not as good as some more expensive cameras. I haven't found a comparable camera that does better, but there seem to be cameras is the $300-ish range that take significantly better low-light pics.
I've attached a pic of one of my fishing spots.
