Millipede trackball

Does anyone know where I could pickup a trackball for Millipede cheap? Happ's wants $100+ for one through them and I haven't had much luck through ebay.

The one I currently have in there works fine, just concerned about getting a new one since the one in there is from 1982.

QuarterArcade have used CPs but the trackballs are probably in worse condition than yours.

They mention a rebuild kit, where you get that from I dont know. Happ maybe ??

Edit: this may do
