'...you can't beat a turbine for reliability...'
Oh, yes you can. It's a common misconception that small turbine engines are more reliable than pistons. It might have been true in the early days of Hiller 12s and Bell 47s, but today the boot's on the other foot.
I think you'll find that while pilots prefer the "sexier" whine of the turbine, owners are much more smitten with the reciprocating version.
Now the EC120, that's another league again...
