Spaceball 4000 FLX with OrbShield and a Microsoft Trackball Explorer
Also a reclining gaming chair.
Think of Lawnmower man chair, with 2 side tables, left hand side is Spaceball 4000, right hand side is Microsft Trackball Explorer.
No need to ever use the keyboard.
It is almost like driving a car with 2 stickshifts.
Very comfortable and ergonomic.
It requires a little bit of mapping keys in the Skyrim keyboard mappings and the OrbShield so that you can use all the spaceball 4000 keys.
The Microsft Trackball Explorer has 5 buttons and a scroll wheel, and it one of the best trackballs I have used.
