Yes, I know they're twice as much - even more for the bigger one. But like you mentioned, they're arcade units and really tough, but more importantly, they're rebuildable with spare parts.
That means instead of buying a new trackball you can just replace the ball, the encoders or the bearing shafts. It might be cheaper long-term, and they've been making that same trackball for over 20 years so its not likely to go out of production anytime soon.
Something to consider.
they also seem to have a translucent ball kit for that same part (at least, it looks like the same part):
which satisfies your backlit criteria.
gum? why would someone do that? it's so nasty!in fact I often find people who chew gum generally offensive as apparently closing your mouth and not making smacking noises is difficult.
gum? why would someone do that? Buncha savages in this town.
I vaguely remember seeing one of the images on a popular website recently, but I can't remember which one. I think it was a blog of some kind. Anything interested in the referrer logs?
Probably aminaked and its pic directory browser, nakedbrowser.
In the future, kiosk trackballs will instantly change chemical composition when removed from their housing, so they are highly adhesive, and will explode in two seconds. That would probably solve the problem.
