Simulators can be usefull, and many recomend them. I personaly do not like the simulators as they do not fly exactly as the real thing, and why sit at a computer when I am trying to find something else to do any way. (I work with computers all day)

In my opinion, the simulator is a great way to learn the basics of how the controls work, and even some of the basics of flight. However, I think the money is better spent on a trainer. Then find yourself an instructor and go fly.

If you buy a simulator, I would go with real flight.
