The EF-S 17-55 f/2.8 IS USM is an expensive lens, not doubt about it; but in my opinion the price/value ratio makes it well worth the price.
Is it more expensive than some L-series lenses? Yes. But you're getting a wider aperture, really good glass, and image stabilization for those extra dollars. Right now, nothing else compares.
For some, the faster aperture and IS aren't worth the extra money, but for others it might be.
Some have questioned the need for IS on a short tele lens, but again it's a case of specifics. A few years ago I was shooting the wildlife at Walt Disney World's Animal Kingdom. I was really enjoying shooting from the moving vehicles...until I looked at my shots on my computer. The trucks don't stop for photo ops, and the vehicle movement was clearly evident in the many blurred photos -- almost half of my shots were unusable. If I had had IS, I think the number of usable shots would have been more like 90%.
Another place where this lens would shine, in my opinion, is for candids at wedding receptions and other events where people are moving about and the photograper can't realistically use a tripod. Again, the extra stop of light gathering, the narrower depth of field (for isolating the subjects), and the IS could be worth their weight in gold.
Of course, the OP said his goal was mainly architectural shots, so IS and narrower DOF might not be justified in his case. If a 24mm maximum wide angle (38mm equivalent field of view on a 40D) will work, then the 24-105 f4L might be a good choice.
In my case, a 17-55 will stay on my 20D, and when I get my 3D in January or February I'll start collecting L-series lenses for it.
