I've got an old Canon Rebel EOS Xsi 450D dslr and it will have have over 10,000 shutter activations on it by Saturday evening. It's been really used hard, in the rain, freezing temps, sleet, and the scorching, high humidity heat of the southern US..but its still going for now.
I don't know what I would buy if this camera gave out on me. I have not even looked at what is out there now. I do know it will be a Canon because I have so much money invested in Canon compatible lens.
I'm going to drive this one until the wheels fall off.
