My mistake, thought it was analog - its been a while!
Ok, that sounds like the interface for me
And that stick with replacement housing looks incredible
Now, what spinner and trackball do I want
Im looking for excellence, with no corners cut for these two
When I breathe on them, I want them both to spin for 20 mins

Is the Beston HI-Ring Universal Arcade Trackball a decent 3" option?
and for spinners, I have no idea
