We always opt for the Cadillac solution when a pinto will do. The caddy costs more, takes more fuel and oil to maintain and requires a specific caddy mechanic. Too expensive and time consuming.
They don't need fancy helicopters. They need something they can jump in and go. IIRC, a slick, (seen below) took 12 hours of maintenence for every hour in the air. But don't quote me on that. They were very good birds.
