Commanders are a great choice. They're roomy, fast, long range and can get you into fields most turboprops wouldn't dare to even overfly. Just make sure you get the later Garrett dash 10 engines as the early ones are harder to service. The Garrett has greater TBO than any other turboprop, if I'm not mistaken. But it's a big aircraft, so you're hauling a lot of empty seats around and the associated fuel burn.
