ok givin your budget I would suggest the himoto rxb-1...its around $330 us and I think that converts to under 550au...I have one of these buggies and have beat the tar out of it and it ask for more...it handles well and a breeze to maintain...you will most likely have to order parts online but I have heard from others down under that they get their parts pretty fast....but to be honest the only parts that I broke on mine so far is from jumping it approx 12 ft in the air and landing on the throttle (broke one tooth off the rear pinion and the center diff planetaries were messed up, but it still ran)...total cost to repair it was under $15..if you dont get totally crazy with it I dont see how you would need alotta parts..It's a very well built buggy and worth way more then I payed for it...I would suggest emailing them and seeing what the time frame on receiving parts would be.. Also himoto has its own support forum here on rcu with a buncha guys eager to help new rc owners...come by and check out the forum.. http://www.rcuniverse.com/forum/foru...smode_1/tt.htm
