Thanks, Andrew, Ian, Jeff, Robin & Matt.
While researching Canon EOS Lenses I came across this excellent and most informative sit on Canon EOS Lenses
http://photonotes.org/articles/beginner-faq/lenses.html
I have decided on the 450D with a Canon EF 17-85mm F4-F5.6 IS USM lens.
Call me old fashioned but I feel much more comfortable about being able to at least talk to the supplier by phone, than purchase from a faceless site on the net. We have one supplier in Broken Hill that I will give the opportunity of matching dd digitals price othwise I will order it from Sydney.
Thanks for the help
Regards
Trevor
