compact trigger joystick - cocktail??

[vettetekk]

Hey guys,
I am looking to add a trigger joystick to my cabinet. I do like the tron style stick, but the placement for it is directly in front of the monitor, and it might irritate the view of the players. So, I remember - back in the 80s I could have sworn I saw a zaxxon cocktail machine that used what looked like a pacman style ball stick with a button in the front of it. I was kinda looking for something like that. Anyone know of anything like that?
thanks,

EDIT: I did a quick google and came up with a cocktail version of tron that had it as well. I attached a crappy pic to explain. If you look close you can see the button protruding from the front of the stick - ball.
thanks again!
