Did you see the post I wrote above your response? Evidence. Tons of evidence. Go for broke. I'm actually
not here to do your homework and decision making for you.

If I want to use these lenses with my 450D and later on if I am using a full frame sensor, I think best option at this time would be EF 17-40 f/4L USM

Thing is, the 17-40 is only f/4 (not f/2.8) and unstabilized. The thinking of "I need it to work on a full-frame, too!" depends, I think, on how SOON you plan on moving to full-frame. If the timeframe is more than a year, I say go for EF-S lenses all you want. Lenses tend to hold value relatively well (check out the used prices vs. new on the lens you're interested in). You can think of the price difference as your "rental" feel for the time you're going to use the lens. And, of course, if you plan on holding onto your crop body after you get a full frame as your second body, an EF-S lens can still be useful.
