Keep in mind you're buying into a system. You're going to want additional lenses and maybe a flash, so I'd look at both systems and decide what you think would better suit you over the long term. Both Canon and Nikon make great cameras, they're both good, just different.
That is true, the both make great camera's. I've used Nikon all of my life, but I've been tempted with the better resolutions and other factors to switch to Cannon, BUT my family has mostly Nikon, so I've already got lenses for them. Tough call.
