Has anybody got a good site where I can compare Digital cameras with each other-pref Ultra-digital ones.?

www.dpreview.com

Da best

Try http://www.dpchallenge.com

It is a digital photography contest website, but they have a very good section providing user comments for many (dare I say most) digital cameras. You also get to see the work of some people using those cameras.

You can check out basic details and find the cheapest prices at www.pricerunner.co.uk

The best I know of is: www.crutchfield.com

reviews.cnet.com/Digital_cameras/2001-65...

PCWorld.com

my favorite for comparisons is:

http://www.dcresource.com/

Another one that has some good reviews too is:

hope that helps.
