If I only had $1K to spend on a camera and lens, then I would not be looking at a 40D.
I would be looking at an XTi (or XSi) and a better lens. From all accounts that I have read, the kit lens that comes with the XTi (the IS one) is pretty good for a kit lens.
Spending ~$800 for a body and slapping on a $300 lens is the wrong way to go, imo.
I personally use the XTi, and spend the money on the lenses. I have a Sigma 10-22, Sigma 30/1.4, Canon EF-S 17-55IS and the 50/1.8.
So, if you are going to switch, I would suggest an XSi and the Tamron 17-50/2.8.
