Thanks for the replies.
Geoff, with your 90-300mm lens trouble, was that a canon lens or a different brand. Ive been doing a bit of research on the cameras itself but when it comes to the lenses its a bit of a Grey area.
General question, what would the main difference be between the 450d and the 40d. I know the 40d has a lower megapixel but the same size sensor (im assuming lower noise across the chip) besides this most functions seem the same.
Cheers
Scott
