I have a brand new 2.25" Ultimarc trackball for sale. It has a red ball. It is in brand new condition. I purchased this for my Centipede but ended up using a Happ after mis-diagnosing an issue that turned out to be my PCB.
On Ultimarc's site they go for $38.00 + shipping...
You can have this one for $38.00 shipped...
Again...this is BRAND NEW...
