Andrew the d-d-photographics are "grey imports". This is not a problem if it doesn't break or you mod the camera front IR filter and you weigh this up against the fact you are getting a cheaper product .
But, due to the dollar down turn I have found that there is currently very little difference between "grey import stock prices" and Australian authorised products (although that said that price you stated is $100 Aust cheaper).
I just picked up a 450D (and decided against the 1000D for many reasons), "non-grey" and believe me I priced 1000Ds and 450Ds for the best price. I've very anal on matters like this.
Anyway the best "non-grey 1000D body " is Scorptec, $699 or Ryda $685:

If you want I can post EOS 450D prices or places to look, which took me Weeks to research! If anything my research may help someone!
