I have to agree with longboarder, the Cheyenne 3 is an orphan. We have one, it's a nice aircraft but parts and support, including training is a pain. If you are really looking at alternatives to the 200, I would look at the Citation 1 and 2. Price wise they are in the same ballpark as the 200. Faster, better altitudes, better operating cost per mile. Down side is that they are smaller inside, insurance will likely require two pilots.
Just a thought.
