Agreed. Turbines are most efficient well above normal GA altitudes. At
common GA altitudes they suck large quantities of fuel. A turbine powered
Luscombe project used to be based at my field. The speed and climb were
slightly better than a piston powered Luscombe, but the range was
dramatically shorter.

While you can burn almost anything in them, you should plan on burning a
lot of it. That was also one of the downfalls of the early turbine powered
cars (besides the initial expense).
