With the upcoming world events and a increase of the prime interest rate (due in a few weeks) and other things that will cause the $US value to rise against the $Aus, it seems as thought the $Aus will soon get to the value of $US 0.630000 which will make the Taipan 4.9 cost $US 10,710.00.
That's about what it was when I bought my Taipan--still a lot of dough but a great value at a few thousand less than the fx-1 or i17r! I think part of the F16 appeal can be that it has F18-like performance at less cost, less weight, and with more versatility.
