well considering you're a pom
have you thought about schumackers new buggy? it's called the swift pro 2 and it is the cheapest bugy i have seen on the net at $250 us and it looks like it has some good features like a 1 peice alloy brace at the rear, carbon fibre top deck machined towers and lay down steering servo.
it is shown in the pics with hudy type brown anodised towers but the rcmart link below shows the car with standard silver.
this link below seems to be the cheapest place that sells em.
