Just to nitpick for a second. Jerez boasts a HS125 simulator which is a FULL sim, on hydraulics, which has been approved for actual type training so it does actually fly just like the aircraft. OATS have a 'simulator' which has been designed to look quite like a 737 and to behave in a similar way.
The first is a very expensive piece of kit and the latter is less so.
But then wannabes are very impressed with how 'cool' the flightdeck looks.
My advice. Go modular, use the cash to pay for a type rating - its working for increasing numbers of people. Sadly.
