I'm still using the same Saitek X36 I bought way back in Beta Tour 3...
One of the hats doesn't work, although I actually haven't taken any time to fix it (probably can)... both springs in the joystick base have busted... the first spring busted and I replaced it with a stronger one from a CH stick... I had to cut it down to size, but it added more tension and a better feel than the original springs.
The second spring just recently broke, I repaired it by manipulating the size of it and adjusting one end to give it a hook.
Y-axis is much looser than the X-axis until I can find a better spring.. but otherwise, it's still going strong.
One glance at it though, and you'll notice the ravages of age have taken their toll on it.
