I bought my controls from OZ Stick about 1 year ago, I live in Melbourne so I actually went out to their office and purchased my controls in person.
I still have the owners contact number and email address if you want me to try and get in contact with him for you.
I concluded as well it would probably be cheaper to purchase the controls from overseas but I like trying to support local businesses.
Let me know if you want me to try and help out waldo
Cheers.
