I use my Canon 17-55 f/2.8 IS most of the time, but sounds like you don't want to spend $1K for a lens. Which is perfectly understandable.
I mention this because I upgraded from the 18-55 IS - within its obvious limitations it's very nearly as good optically as the 17-55.
In fact, it's good enough that I kept it after I upgraded and use it when I want a more compact package (such as packing camera gear in my motorcycle tankbag).
So I join in recommend starting out with the 18-55 IS.
