With all the great cameras available, I'd like to suggest checking out
www.cnet.com. They have reviews, ratings, price comparisons etc. for various products, including the cameras mentioned in this thread. They've been a big help to me in finding things in the past. When they give the price ranges for different items you can click on "check prices" and a page will come up telling you the various places that the camera can be purchased, for how much and information on the store. The store info includes a profile on the store with such things as a store rating, restock charges, customer service, store policies etc.
