There is also Flightgear, a free, open source flight simulator. It's a very capable program.
Re pedals: Why is that some of the most common sim pedals on the market are....wrong? They're obviously designed for the user to rest his or her whole foot, heel included, on the pedal. Some even have a lip at the bottom to stop your foot from sliding off. Not exactly the correct way of using real rudder pedals ie heel on the floor far enough back so that the brakes aren't being ridden, with te ball of the foot on the pedal
