right now I have a Canon EOS 10 D but i will sell it soon. Ther camera is great and the 20D is even better.( I'll bought something else but this isn't important here/ still canon) Yes the nikon is cheaper. But I would prefer a 20D. Now why would I give you the advice not to buy a 10D ? Ok not because the 20D has 8 instead of 6 Mp, but because it has much lower noise. The Sensor is new and really better. So it really depends how much you wanna spend if you want it really cheap you could get a Canon 300D still very good camera and very cheap also compare to the nikon.
