DC header (Plus shipping) to Sydney from the States is about est USD$400. That is about AUD$535. Compare to what shebangs said, it is a pretty much a mid-range header but looks like no one has them in their car. That is pretty sad.
Well, I have a mate to tell me all the time....
"Price will be soon forgotten.... Quality will always be remembered".
Also to spend over $1k on the header only is way too much! So Toda is out of the budget!
I am still hoping for someone with DC header to tell me more about the product! :)
