I've used an X-52 (non-pro) for, must be 2 years. Prior to that had gone through 3 Saiteks in 18 months, with the replacement plan through best buy. Never used the twisty, as I have the same coordination affliction as Ghosth --- and kept twisting accidentally in combat.
Used CH rudders and love them. BUT -- within 4 months of getting them, a potentiometer went bad, wouldnt stay calibrated at all. Since shipping would have been expensive to get the "free" warranty service, I opened the rudders and switched the pots on the rudder and the toe brake (since the "center" was going on that pot, and center position doesnt matter for the brake) Get an oocasional spilke, that's it.
Biggest advantage I see right now is that the CH pots can be purchased for $8 or so, while the Saitek needs a whole new stick. That being said, when this one goes, I'm buying a CH stick.
