Here are some sites that you can get reviews on cameras, lenses etc.

http://www.the-digital-picture.com/
http://www.dpreview.com/
http://www.steves-digicams.com/
http://www.dcresource.com/
http://www.luminous-landscape.com/

if you have any other sites you want me to list here just post them and I will add them to this first post

http://www.steves-digicams.com/
http://www.dcresource.com/

Those are by far the best. My personal fave is Dpreview, but the others are a very close 2nd place. Hair splitting at it's best!
