Firstly I'm gonna ask if it is really more cheaper to build your own controller than buying one, I live in Finland, so keep that in mind. If building is cheaper then could somebody help me with this: I checked this page:
https://sdvxii.pancakeapps.com/ but they didn't mention if the parts contain the required wires so I'm not sure. And do sanwa's buttons have omron switches already, because they only mentioned that "Use the switches that came with your Chinese buttons or upgrade to Omrons", nothing about the sanwa's buttons. And lastly, anyone know some good actual tutorials how to build one, prefer videos but text is okay, pictures help too.
