UH- I would stay away from those simulator courses. These courses in my opinion are a waste of time, and money. Let me explain when you graduate from college you will more than likely start flight instructing, build some time, and move on to the regionals. Flying a 737 simulator in college will not help you land a job after college. In fact at 250 hrs you have no business flying a 737 simulator at all! What I am saying is that you need to develop your flying skills. Start off flying PIC in an airplane you can handle, and eventually you will upgrade to more complex aircraft, and when the time comes that an airline asks you to fly a 737 for them, then let them pay for your 737 sim training.
