I mentionned it before but there is a great website to see the ratings of photo camera: Snapsot! Snapsort allows you to rate and sort cameras based on color depth, dynamic range and iso sensivity, among others. Which in my opinion is the right way to choose a camera, not just the number of pixel but the quality of those pixels!
I alway keep an eye on the site to see new cameras and how they rate agains previous ones. Cut through the hype and see the facts ;)
Right now they are running a contest to win a nikon, check it out:
