I forgot to answer this one--
Great plane; I've had it 5-1/2 years (during which time the FSDO never checked on my RVSM and MEL by the way). As a jet, it gets the advantages of quiet cabin with no vibration, weather-topping, high cruise speed (370 knots) and system redundancy.
Because it is small and fuel efficient, the direct operating cost (by which I mean fuel plus maintenance) has been about the same
per mile as I was paying when I flew a Cessna 340. The fixed costs (capital and insurance mostly) are of course higher than a twin Cessna. And then there is the matter of the periodic engine costs (hot section and overhaul, which are certainly higher than for a twin Cessna).
But it's a pretty cost-effective jet that is very reliable and a blast to fly. With the side stick, you can quite easily feel like Tom Cruise in Top Gun. And there is something pretty cool about flying in airliner country:
Thanks, everybody, for the words of advice. If anything unusual comes out of our meeting, I'll post it here.
