Camera Suggestions! Please

I need a good camera. The bigger body ones. Not the thin little one. Something by Nikon or Canon.
I need one for GOOD and CLEAR photos.
I do self photography and nature.
Highest price can be $450.

For that money the best you can get (new) is a Canon Rebel T3.
An used Rebel T2i (without lens) can be found for $500 and is a much better camera.
