Building a stationary gun cabinet

[jkl]

Hi,
I'd like to add guns to my LCD cab project.
I'd need a stationary gun (X/Y, i.e. I think pot guns) system, such as Revolution X.
Anybody can advice me where could I get it (Europe preferred)?
If I purchase a non working unit, how many chances are there that problem are weared out pots?

Many thanks in advance.

Replacing a potentiometer isn't a big deal (chepa and pretty simple). Finding a positional gun(s) in good condition (gears and bearings etc) might be harder.
