Welcome to the forum. It helps if you go to the User Control Panel and add your location, that way it shows on every post, and helps us give location appropriate advice....
I agree with BM about the chair probably not having much option for improving it's abilities - the China folders are all fairly similar and have the same strengths and weaknesses. Great for portability in a car, possibly air travel, but not so good on getting around IN the chair....
Generally you can change the knob on a joystick to something that better suits your grip, but it is important to note that any of the electronics parts will NOT interchange easily, as there are several different manufacturers and model "families" of the controller / joystick / etc. electronics systems and you can ONLY swap parts if they are all from the same type of system (such as "R-Net" which is one of the better systems).
Since your chair is almost certainly made with a control system that is not one of the usual 'families', it is very unlikely that any of the joysticks you see on Ebay, etc. are going to work....
If you just want to change the knob, the only real concern is that the diameter of the new knob's hole matches the diameter of the shaft on the joystick, or you have an adapter to make it fit....
