Hate to say it but I got a friend that has a 60d and we go shooting together a few times a year. He has no idea what he is doing with his gear and wont accept help from someone that has "a cheap T3". When I show him pictures I took he wants to know what presets in LR I am using and my tricks lol. Comes down to a Pro can take better images with a T3 then a newbi with a pro body.
Its a tool, learn how to use it correctly to do your job and your set. Sure better newer bodies would be great but not everyone has the money or the need.
The T3 is a fantastic entry level DSLR, I am sure tons of people started with a Rebel body before moving up in the world of canon bodies.
