I want to buy a Canon DSLR camera. I'm interested in doing mostly narrow-angle shots. My budget is up to $250. I was looking at used Canon DSLR's, namely the Eos 10D-60D. Is there a camera in this range that you would recommend buying/not buying? What is the best used Canon DSLR I can buy in this price range? Used ones are an option for me - the 10D caught my eye, as it's older but seems to be a solid camera.
