Canon Pentax Sony

Canon Pentax Sony
I would buy a Digital Slr of my bf's b-day, but I'm not sure what for him. Can anyone help?

This would be its first digital Slr Camera. He has a Sony Dsc W series before. I'm thinking of either Sony, Canon and Pentax. Could someone recommend me a good one for beginners. I can AFORD until $ 600 for it. Thanks!

The majority of the camera for the $ $ is the Nikon D40 with 18-55mm lens .. less $ 500 … you can buy extra memory cards with some of the money to spare (1 GB card sold for about $ 11). To view more: http://www.jdpower.com/electronics/ratings/digital-camera-ratings/dslr
