I assume that's an X-Arcade stick?  
You'd probably be surprised at how little is needed to keep the controller in place.  I mounted my tank stick to a pedestal using nothing but the stick's own gravity and some holes.  On the top of the pedestal, there is a board that sits underneath the X-Arcade with 8 holes drilled into it just large enough for the X-Arcade's rubber feet.  When you place the controller on top, the feet fall into the holes and the box appears to sit directly on the mounting surface.  I wanted it to be easy to just pick up and take the controller from the pedestal whenever I want, and it has worked like a charm for 3 years and counting.  No velcro, no fasteners, etc.  It doesn't move around one iota, even with 2 full grown men playing Street Fighter 2.
