One important thing to remember, is that the Australian dollar has gone from $1.12 USA and slipped back to $1.03 etc.
That $5950 price wont last 4 ever and will slowly creep back to the $6600 ish mark if the dollar keeps sliding.

Also, that sub 6 grand pricing also capitalises on the fact that all the machines are arriving in seafreight containers. When the orders go back to airfreight etc, the excellent short term $5950 pricing has to change back to the much higher pricing if my calculations are correct.
