I met these guys when I went to the Cockpit Fest at Newark Air Museum in the summer when they had a couple of their airliner cockpit sims on display for us punters to try out. They sold me MS FSX Gold for a discount price
and it works a treat on my PC with my Virtual Pilot Pro!
If you are wanting to get into serious Flight Simming then I suggest you check them out for ideas- some of their cockpit creations are truely amazing.
