Hi Ferry Pilot,
In a former life I operated an AS350B2 and B3 and the Turbomeca is very expensive to operate if something goes awry let alone routine maintenance.
Have you thought about the AS350SD2 which has the lycoming LTS 101-700 engine conversion same horsepower as the B2 but with the lower fuel burn and much cheaper operating costs to the Turbomeca, its worth checking out.
