I’m not aware of any that are kept reliability in stock. You can get new sticks, gears and bowls (plastic ones that will have the same problem over time, but much cheaper). I would get new sticks to go with these bowls. https://store.kitsch-bent.com/products/n64-joystick-thumbstick



I go through different switchers to various inputs of the retrotink4k. I avoid composite to keep it simple and get a better picture.
