Alright thanks people. The lack of IS on the lens has me a bit worried. I think I'll invest a bit more for the IS model, although it does seem quite a bit more pricey compared to the non-IS.
I'll see if I can borrow mum's Canon EF 100-400mm f4.5-5.6L IS USM and see what it's like with IS turned off to get a bit of an impression of what the 70-200 is like without IS. Although she still hasn't allowed me to touch it :(
I see that a few of you guys have bought second hand before. So what about this http://www.ebay.com.au/itm/Canon-EF-...44795564923666
As a uni-student every bit counts, and so long as it doesn't have damage (it doesn't look like it) then I am happy buying second hand.
Cookie, enjoy the DSLR man :) You will love it. A 450D is a great camera to enter the DSLR world with.
