I can answer all those questions for you... If you buy from England the course will cost Approx A$800, from within Australia A$620 From LSC A$590 (if sent airmail) A$720 if sent DHL. E-bay is linked to America so savings can be minimal, if the course shows you lack the support and have no refund.

Point to be considered if you buy from LSC you have the money back guarentee... (extendable if required) Outlay then is the cost of return postage.
