If you are looking at the corporate market, you may find that over the medium
term both the piston and turbine products are on their way out. The silk suits
only want to fly jets. Even the general public has developed a deep seated
suspicion of anything with a propellor on it, and most regional operators are
in the process of replacing their turboprops with jets.

The flying public does not understand that a propellor is an inherently
efficient propulsion device, particularly at low density altitudes, and as
such well suited to short haul operations. Thisd misunderstanding may do much
harm to general aviation, because the advent of jets at airports currently
served by turboprops will increase noise complaints from neighbors.

I know one company operating KingAirs and Falcons, and they say the KingAirs
are logging very little time these days, despite the higher price for the
jets.

Unless you have some sort of captive market - an existing freight operation or
something with some sort of protection from competition built in, I don't
think you'd do well tio invest in a fleet of Navajos or twin Cessnas (unless
they're Citations!).
