Which brand and model is the best for digital camera?

for me it would be about sony probably

Canon A640. Canon is rated number one is consumer reports for their point and shoot cameras. I had to do a lot of research on digital cameras. I bought this one for my mom for Christmas. Here is what it is all about.

Hope this helps.

Canon Digital Rebel, it runs around 700-1000 dollars but is well worth it. I've taken crystal clear images from a car going well over 70 mph. With the accessories, filters, lenses, zooms, etc, you can capture a lot of decent shots

Depends on what's in your wallet.

$600-$900 - go with Canon Rebel or Nikon D80.
Less than $600, Canon S2IS.

Under $400 you have a wide choice. It is very difficult to recommend without knowing your budget.
