I always remember a friend of mine saying "I won't hear a bad word said about the S76, the overtime is paying my mortgage"!!!!!
I somehow doubt that the S76 will ever be cheap to operate. Anything with twin engines costs and labour isn't cheap. Really down to how deep your pockets are.
There will no doubt be some cheap(ish) Lama's on the market in the next few years.
If I could afford one I would. Very reliable.
Some 47 parts are hard to find or very expensive or both.
