Our company operates XLSs. I have been to both CAE and FSI, and (this is just my personal opinion) I feel like both places charge way more than they're worth. I'm guessing that an initial at FSI will be in the high twenties as far as cost goes with CAE being a good bit cheaper. We use FSI since we are on a Full Service contract which allows us to train as much as we want throughout the year. Both places will get you through the type ride, but the quality of your training will depend on who your instructors are. Good luck.
