Query: Canon EF-S 17-85mm Lens

I bought this lens as an upgrade to the 18-55mm lens that came with my Canon EOS Rebel XTi camera. It is quite a nice improvement, noticeably wider lens and heavier, denoting higher quality materials throughout. I think it will be a real good "all around lens" with more zoom capability. I have only taken a couple hundred outdoor pictures and am pleased, I havne't gotten to test out the image stabilization in low light/indoors. Overall, I'm impressed so far and feel that I now need to upgrade my camera to the Canon 40D to get more out of the lens that I've upgraded to.
