Fraaaaank!
As far as twisty-sticks go, you can adjust the scaling and deadband a lot to help you out, but in the end you have to live with cross-input. Not because of the stick, but because of human ergonomics while USING the stick!
Get a cheap, old, used, whatever, pair of rudder pedals if you can. I have 10-year-old CH gameport pedals and while nothing like the slider-pedals nowadays, are waaaay better than twisty ever was for me.
