As a real world pilot, and an avid flight simmer, I would love to have a multi million dollar simulator like you might find at, say, Boeing.
For my home flight simming, I dont even have a yoke. Just a joystick. I admit I would like a yoke, pedals, and a 4 engine throttle quadrant, but I agree that buying all the radio stacks etc is a bit much....
Also, those spending hundreds of dollars on home flight sim products might want to consider a trip to the local flight school...you might well be able to afford a bunch of hours int he real thing!
