I've had my CH stuff since around 2003. The Fighterstick and Pro Throttle do everything they originally did and I have no regrets in dropping the money on those.
The only issue I had was with the pedals, which I no longer use (although I still have them). The wiring inside was a little shabby. After about the first year of use I started having problems getting them to work. After opening up the unit I could see the wiring had not be down well or secured away from the moving parts. This combined with the poor design of the USB cable connecting point to the pedal base really disappointed me. I fixed it a couple of times, but it just really stopped being worth it to me. So, I just use the little joystick on the Pro Throttle to control the rudder and I have the brakes programmed to the hat switch (which works perfect).
The only thing I could say I would love to see improved is the spring in the Fighterstick to be a little tighter (or at least allow for an adjustment). It centers fine it is just a preference thing (I would like a little more resistance).
I know they are not for everyone and not everyone's experience will be the same, but I recommend the CH Fighterstick and Pro Throttle. They have been worth everything I paid for them!
