there is your calling mike,go for it mate.aussie/china pin for the world.i'd buy one.
An Aussie mate of mine lives in Shenzhen and has a large factory making garage door openers. He has all the equipment including 4 new plastic injection machines.
His factory has an empty floor in the building that is HUGE - he has offered it to me at a stupidly cheap price to do exactly this.
I'm not ready to take that plunge yet.
Time, money, expertise - all light on at the moment!
