Good summary.
I actually have to back-track a little on my previous post regarding 2 things...
1. I can actually have 5 simultaneous keys per player, not 4. Even with fighting games, you're not likely to have to use more than 5 switches at once. Worst case scenario that I can support per player is a diag joystick direction (two switches) and 3 action buttons all at once. One weakness is that the 2 modifier keys are permanently mapped to buttons 1 & 2 (most frequently used), but the other 3 slots in the buffer can be used for any of the other keystrokes (buttons, joysticks, spinners)
2. i-pac does not seem to support analog (that I need for the spinners). I saw that they have an a-pac, but the Price is way too high. So, I think the Teensy was the best choice for me - does digital and analog inputs for 20 bucks. Plus can be used for other projects.
The pool balls are supported by the heads of the 3 screws. I used a dremel to grind the heads just enough so that the contact with the ball is smooth and doesn't scratch. The balls work very well. When I took the photo, I forgot to turn the power on so that you could see the cool red glow from the mice LEDs shine around the trackballs - just a pleasant side effect.
And if pool balls are TOO decorative, just pop in two cue balls.
