I've build two arcade control panels with sticks and pushbuttons and I'd like to build a Spinner. What's the best option. Do somebody sell already made spinners including everything ready to work, with the case or not? Or do they only sell the knob for those who want to install it with a hacked mouse. Also, what mouse would be best for hacking, optical or ball mouse? Do you recommend me the optipac? Could I build a spinner using a dial radio knob or should I buy a fultra or oscar spinner?
