It's not a question of which camera to buy, but a question of which SYSTEM to buy. Once you select either Nikon or Canon, you'll have so much invested you'll probably never change. And more important than the camera is the glass. While Sony may have some impressive new cameras and lenses, you won't get the incredible selections of lenses that you get with either Nikon or Canon.

Myself? I prefer Nikon. I've been shooting with Nikon cameras and lenses since I was in high school. I think their glass is the best in the world, and I love their cameras.

Agreed. I've bought 2 Nikon cameras and numerous Nikon lenses factory refurbished and haven't been disappointed with a single one. I have yet to experience any warranty issues.
