You can't keep flying a 40 yr old design forever....one has to move on and invest in technology with all its merits
If I was a Playa........I would have bought a 407 when it first came out. Since I have a saying etched in my brain. "Never buy an A model of anything" I waited to see how many of the "Rollers" paid for the ADs that would surely come out, and they did.
Now its a bit better, someone else suffered the problems and its a great purchase......
Same thing flys with the EC-120. Let someone else do the testing and since I see a few more buying the farm recently it is not over yet. Then maybe.
As to purchasing "new" only a proven aircraft and only then if I cannot find a clean machine that someone else has eaten the initial depreciation.
If I had the ability to purchase anyway...........
