I've been using various FS for 10 years. They kept me 'current' when I took a dosh (lack of) enforced break from my training, but I found it invaluable as part of my IMC course. I could practice approaches, holds etc FS 95 & 98) and now fly the FS 737 for fun practicing SIDS and STARS etc. Well worth the investment.
No doubt Saab Dastard will now tell me I need a bit of kit for my pooter to improve the speed of the graphics.........
