Bell placed first in the ProPilot survey and MD place a distant last...
Did you read this? You might want to read it again and think carefully about the implications. I have no MD experience but do operate a 407 and can attest that Bell support and training have been superb. It would seem that the 600N has achieved near orphan status and could be a true orphan if MD doesnt make it. There are more than 1000 407's flying vs a handfull of 600N's. You can no doubt buy a used 600N at a relative "bargain" price, but it may not be a real bargain over the long term.
