I have the CH yoke, Saitek Rudder Pedals, and Saitek X52 joystick+throttle.
The yoke feels real when you hold it, but of course feels nothing like the real thing when as far as the performance. Pull back on the yoke just a tiny bit and the plane is all over the place.
The Pedals aren't very good, they feel way too light and slide across the floor, I had to shove books between them and the wall to keep them from moving. They lock up now and then and I have to unscrew the case and put the wheels back on the sliders inside. Plus if I tap the toe brakes, the brakes lock.
The X52 is awesome. The joystick is really comfortable, and a lot of fun to play around with. Also the hot switches are pretty cool. It also comes with a fighter-type throttle as a separate unit. It can be used independent of the joystick and I often use it with my yoke. Its the only product I own that I'd recommend.
FS was a lot more fun before I ever touched a yoke in real life. Its still fun to dick around the FS world, but of course its nothing like the real thing.
