I have done BE-200 training at both Simcom and Simuflite and have been pleased with both. All of my instructors at both places have had substantial experience in the actual aircraft. Simcom is cheaper, has small classes (max 2 folks), and you'll have the same instructor throughout ground and sim. Their sim also has a GPS in it which is nice.
Simuflite has a full-motion sim, but it doesn't have GPS (they were talking about adding it) so you're flying the old-fashioned way ... a big change from our dual-IFR GPS cockpit. Larger classes, multiple instructors (I had two ground instructors and a third guy in the sim in a four-day recurrent.). All the instructors were knowledgeable with experience on the aircraft. Simuflite offers some "free" (included in course price) optional courses in the evening that can be interesting and informative ... we did a TCAS/GPWS module and a Security module at our last recurrent there.
Both places have good teaching materials (books, displays, etc.) that are good library material after you get back from the schoolhouse.
I like Simuflite better for the motion sim and the fact that Dallas is more fun to hang out in for a few days (but then I'm a Texan at heart), but either place will take good care of you, and they're both cheaper than FlightSafety. FSI does good work, but they do often have instructors with no experience on type. In my opinion, not worth the extra money.
