FlyRight, Inc. just got their Level D full motion King Air 350 simulator online, and approved by the FAA for everything, including Part 135 checks and initial. Their customer service is outstanding, sim is outstanding, pricing way better than FS - they are a boutique shop that specializes in KA training, and they excel. Their instructors are current KA pilots, not sim instructors from some other airplane.

Worth a good hard look, for sure.
