I have used Ch products for about six years FSPTPP , never having to replace anything very good stuff.  I recently had some issues in game with settings and assignments and found that if you are using the control manager software to assign keys and axis there are conflicts with FSX. Not running the ch software and using plug and play and setting everything up inside of fsx resolved all issues.
I needed a flight yoke and was about to buy the new ch eclipse when i decided on the Saitek system instead. the flight yoke looks and feels very realistic the throttle is also well made and the levers look and feel more like a real aircraft control lever.Set up was a snap and the game default assignments automaticly assigned all the axis and buttons up and flying in less than 15 minutes. www.provantage.com has Saitek and CH products usually atleast 20$ cheaper than you can find anywhere else. If your looking to buy a yoke do not discount the Saitek pro flight yoke and throttle quardant very realistic and well made.
