I’ve used this site to shop for digital cameras from my very first bricklike 3.1-megapixel camera four years ago. It’s great – overview, shows controls, conclusion, and THE BEST part: sample pictures. He takes pictures of the same things (candy in his office, etc.) with all the cameras so you can compare.
Once you go to the site, go to “Our Reviews” in the upper-left. It makes shopping for a camera so much easier.. Trying to do it in the store is enough to make your head spin.
