Take a look at the
top 10 digital cameras on epinions.com... the site uses consumer ratings, so it's a pretty good, unbiased gauge. However, it is an "all things considered" ranking, so an item's placement will depend not only on how good the camera is, but also it's price, etc.
Top ranked is the Canon Powershot S400, followed by the Minolta Dimage Z1, and then the Nikon Coolpix 5700.
