As for Beechjet flying...

I'm involved in the training process of the BE400 and get to see how a lot of people handle training. I got my type rating with only piston engine experience under my belt without any major issues. The Beechjet is an old school electronic bird. It does most of the fancy glass cockpit stuff new aircraft can do, but it's a bit cumbersome to make it happen. The flight director/autopilot gives people the most trouble. Make sure you know what every mode does and how it captures. The FMS is very powerful and semi-user friendly. I don't have anything to compare flying characteristics with, but it seems fairly decent. It uses spoilerons instead of ailerons which gives it a bit of a unique feel. If you have any other specific questions feel free to ask.
