Eleven? Are you sure? There are 4 or 5 on the production line at any one time. Remember, there are less than 400 total in the world built. When 139 orders dropped off with O&G recession, Koala orders picked up, especially China.
Production line tight for space now in Philly with 139 but also because of 609. It takes up half of the production hall!
It is expensive to purchase but is fast to fly and very responsive. It is actually certified on the 109 Type Cert, hence it carries many systems from the 109 twin (Dual Helipilot, Dual Hyd for instance) as standard. This adds $$$. But you can cruise at 145-150 knots if you like. And carry 8 including pilot.
I'd like to see someone put the HTS900 in it to see how it goes. Better hot and high and lower fuel consumption. PT6 is nice but it really sucks the fuel.
