AMF's training program is pretty good and pilots come out of the 99 training prepared for the single pilot IFR world. I have good family friends at American Airlines who flew for Wings West (Pre-American Eagle) that have the same BE99 tail numbers in their logbooks that I have in mine. They've been around awhile, but still a kick in the pants to fly. They are a good introduction to turbine aircraft for the pilot coming from piston airplanes.
