S300
As mentioned above I can't see it getting any better. I hope someone buys the type certificate and carries this aircraft on. rumours chinese are interested.
Sikorsky really didn't want the small helicopter from schwizer....
Apart from parts that have been mentioned pretty much should be able to get the other items, and yes they have escalated as the old places that made the parts stopped as sikorsky only paid every 60 days, they couldn't live waiting that long. Now there isn't the places making, for instance, drive shafts and blades.
