I have to disagree Igor, if it gets the job done effectively and economically then is a 'real' working helicopter. Any design that expands the roles we can fill in this profession and allow more industries to use and pay for our talents the better.
I'd personally recommend our questioner to go for a turbine endorsement rather than another piston to expand his knowledge base, and to research the area he plans to look for work in. The machine that is used there primarily is the one to pursue.
And on the other point, if you have knowledge of a $150K per year helo job, I'd love to hear about it. From my experience we'd all have to go work for an airline to experience wagwes like that, but maybe I haven't been out and about enough yet...
