If you want to buy gear in Australia. R/C Boat Bitz is a good place to go. Joe is good to deal with. His prices may seem a bit high on some things but you must bear in mind, he's paid all the freight & import duties etc already.

With Offshore, we always make up an order to just under 200 bucks worth of gear so the $30.00 freight is spread over more gear. It's not so bad that way.

Cheers.
