By my calculation you will save A$35-$40 buying from US cf local.
Not by mine!
At the time I bought my units, there were VERY significant savings to be made by purchasing direct from the US. I bought mine from Marv Golden.
The only drawback is with after sales support. You won't get much joy locally if you bought the unit from the US .......... but I have never had a problem with any of the units I have bought.
