Which will be the best site for digital camera advices (what and where to buy the best...)?

For digital, I prefer dpreview.com as well. For underwater, I tend to use wetpixel.com.

In terms of purchasing, I am pretty loyal to the local pro-shop and to BHPhoto.com

http://www.dpreview.com/

I always go to CNet first for anything I want to know about. Digital Camera direct link below.

I have several web sites for digital cameras including prices, previews, photos samples, recommendations, etc..

http://www.photographyreview.com/
http://www.imaging-resource.com/
http://www.dcresource.com/

Also the most popular and best one is :
http://www.dpreview.com

without a doubt http://www.dpreview.com

have to agree with Jeff, dpreview can't be beat for in depth info.

Most of the mentioned sites. But ALWAYS go to amazon and look in the deals section such as the recent one which has:
Canon Powershot SD450
Canon Digital Rebel XT 8MP SLR
Sony Cybershot DSC-S600
Nikon Coolpix
and a heap more.
