Wow, $2,100 and Nikon doesn't even give you a full metal body? I hope Canon isn't so cheap with the magnesium alloy. You can get the 7D for $1200 and the body is a tank. Hopefully the 6D will be the same.
7D, built like a tank, but rebel-like IQ. Even 650D is better.

No need. Sensor is same with 550D unless you dispute it.
