I use the CH Force FX, CH Pro Throttle, and an old, old TM RCS that I have modified to allow me to fly with my heels on the floor. Like Sancho, I like the wider spread and longer throw on these pedals.
As a matter of interest, other than modifying the feet placement, I also removed the coil spring that had a tendency to break with 1/2" bungee cords. The good one's like the truckers use. It gives me more feedback on how much I have my pedals moved because it gets stiffer the further you push em.
I have not had to replace any portion of any of the components other than the spring on the rudder pedals and have found them to be trouble free.
