I've been looking for a trackball for my cp, but haven't come across anything that I really like so far.
I already have a trackman marble FX ball that looks like this.

It does its job pretty well. I've been brainstorming about how to mount it in my cab. It wouldn't be seeing much if any use for games, but mainly just navigation.
Have any of you succefully done this? And has anyone done it without having to completely thrash the trackball?
