Competitive cyclist shipping?

Since 2001, over 90,000 cyclist's have joined Cycling Forums to discuss topics from general cycling to equipment, training, racing and travel or vacation destinations (especially in europe during the tour de france). We also feature an great deals in our online store, 100's of articles, classifieds and product reviews.

I am thinking of purchasing a powertap pro with a mavic open pro rim and 32 dt swiss spokes off competitive cyclist for $975us. How much could I expect to pay in aussie dollars after shipping?

If there was a problem with the wheel I have to send it back to the usa, is this correct? If thats the case I don't mind paying $2000au, for the extra convenience.
