There are too many options for us to just say you need X, Y, and Z to finish your cab.
Read the FAQs and look at the encoder options and control options you have. YOu need to make decisions for yourself. There is no "right" encoder or joystick for each person.
Read up on what each part does, and decide if you need it or not.
As a general guide though:
- you need an encoder for your buttons and joystick
- you need a mouse hack or optipac if you want a spinner and/or trackball (you say you don't, but I just mention it as an FYI type of thing)
- other controls require special interfaces, or at least special considerations (rotary sticks, analog, optical devices, wheels, etc)
- you need wires and quick disconnects for your controls
- you'll need paint and hardware for the cab. hinges, screws, etc etc
- coin door, bezel, marquee retainer, glass for monitor, tmolding... all needed.
Do some reading and you can decide what you personally want. WE can't really answer your questions... we can only give you what WE would do.
