Durability, per se, has never been an issue with previous Saitek joysticks. I've never had one fall apart though I did lose a HAT button on an old Evo. I do find them to get sloppy as the Hall Sensors tend to "drift" in time. I retired my X52 (original flavor) about a year ago and bought a CH Fighterstick, which is flawless to this day.
Bottom line, Saitek peds and the X52 throttle are fine. If they could correct the nose bouce/drift on the X52, they'd have a great set-up at that $100 price point.
I didn't mean to imply the things would disintigrate in your hands, Max

Saitek does have a good, deserved reputation for being one of the better-built affordable models, and in all honesty if they still made the X-45, I'd still be using one... BUT...
The "sloppiness" is not a unique thing, nor a small thing for everyone. I purchased several on E-Bay and found many completely sloppy from the previous owners use. They'll spike, slide out of position on auto climb, etc. They don't, after some wear and tear, (and not a whole lot, in my opinion) provide the kind of precision I like to have. Also, the X-45 starts off with great resistance to movement, and gradually gets less and less, making even going from one of the same model to the next a pain for the next few days.
Anyway, like I said, that's been my experience with their joysticks. Whether or not their rudder is any different, I don't know. It very well could be.
I'm still not suprised at all that everyone says the Saitek's are more comfortable.
