I was wondering if this lense would work on the 450D http://www.pixmania.ie/ie/uk/787971/art/sigma/150-500-mm-f5-6-3-dg-apo.html

The aperture starts at F5 which is something you will never consider again after some years of photography*. Sigma is also known for it's bad quality control (front-backfocus problems, soft image etc.)

My opinion is to keep all of your gear the same brand as the camera you use. If that means saving up a little more or buy second hand, so be it.
*F5 is really slow. Your shutterspeeds need to be pretty high to keep your pictures sharp (a minimum shutterspeed of 1/150 at the 150mm end, 1/500 for the 500mm end for non-moving objects!), a rarity when using low iso's . That would mean cranking up the iso which isn't a good thing due to increased noise. Also, the lens does not start to perform at its best at F5, more like F8 or even more. That means even higher shutterspeeds and or iso's.
My bet would be that this lens is usable outdoors on a sunny day. Other than that, don't blame the camera when results are dissapointing
and i believe you can find hands-on examples of a 450 & 150-500 at http://www.pixelpeeper.com but i am at work and the network-filter is blocking the word peeper, so i can't check that
