Big Dan - I appreciate your comments but the problem we have here in Australia is the cost.  I will use the 7C as an example seems that's what I am buying.  The cheapest I can find it here at a place within driving distance is $350 AU and that is without servos.  Plus they don't have them in stock anyway and that particular shop has lost my business due to lack of customer service ie) replying to emails and phone calls.   The next cheapest from memory was about $355 but again no stock.  Servos are $19 each which adds up to $426 with four servos.

With the Tower Hobbies discounts I can get the same thing delivered for $306  so you can see the savings.  Now if I order a cheaper radio, the savings aren't as great due to the shipping costs so that's why I am going for the 7C and not the 6EX.  I figured I may as well "future proof" myself just a little bit?

Just did some more maths and with Tower Hobbies with the discounts I can get the 7C, 3 receivers and 12 servos for $504.23.   The same gear but with the 6EX instead of the 7C would cost me $469.23.  So I personally think it is woth spending the extra $35.

Thanks for your comments peoples!!!
