Greetings!

Hanaho products...

I have their HotRod Joystick and it is very nice!!! The only reason I do not use it more often is because I mostly play Tempest, and it is just easier with a trackball. I have asked them if they are going to incorporate a trackball or spinner option, but they said they are not planning on it in just the joystick versions. The full ArcadePC can come with a trackball, though...

I think it was a capacitor on the deflection board for the X-Y display that had a tendancy to wear over time. They make replacements for it, and many of the machines out there have been rebuilt. There are a few good pages that you can check. I know that they are not hard to fix, and the parts are available, if specialized.
