Current exchange rate is:
1.00 USD United States Dollars = 1.33138 AUD Australia Dollars

Therefore the $386.75 AUD radio is costing $290.50 USD

That radio system sells for $180 USD here or $240 AUD
http://www2.towerhobbies.com/cgi-bin...=LXHYK7**&P=ML but I realize things may cost more there. This does seem rather high though. You also said 6EXA and not 6EXAS which is an improved version (I believe).

The setup is suitable for a beginner and the radio would also be good in future planes. The price? Well that's for you to decide because most of us don't know Australian prices.

At any rate, I hope you find an equitable solution and join us in this hobby.
