I had bought that Canon D2 IS and it was inferior for night sports. You guys gave me lots of great suggestions, from bare budget to katy-bar-the-door budget and I settled on something that has me really excited (20D & Sigma 70-200 2.8)
I've still got some learning to do, sharpen up those photos a bit more, anticipate the action a bit better, that sort of stuff, but I'm a very happy camper.
Once again, thanks for the advice.
