hotheads are made by a company in SoCal. They have great customer service, and their reputation seems very good. They have just moved to Costa Mesa
I've met the guy who runs it all, and they will ship to australia, and the freight cost was quite reasonable. The setup is just a little too big to fit into a suitcase to bring back as luggage - ask me how I know
Not sure if anyone in Oz is importing them yet.
