Australian pipemaker, Ian Mackenzie has been trading under the name of SIMACK, his website is:

Don't go by the prices shown as they are 2 years old and Ian is having his website re-vamped.
I've ordered a custom chanter that is soon to arrive, so I will post my findings. I verified with 3 of his references in the US, all of whom LOVE his pipes. My last conversation w/ Ian was he has upgraded his sets where all of his chanters will be blocked for future keys and all of the bags will be fitted w/ the cup for future drone stock. This way a piper doesn't have to sent the entire set back to him for upgrades.
Dollar for dollar his prices are equal to the higher prices US sets... it's the conversion of the US dollar where his pipes become more attractive. Last month The American dollar was nearly twice the Australian dollar, but as you have it, it's dropped somewhat... still a good deal to buy but I'm hoping the rates improve again.
