I bought all my stuff at Suzo (Belgium/Netherlands).
- pushbuttons, (STC) joysticks and trackball (Suzo)
Everything works great, the only drawback for the joysticks is the mounting (to have a good fit you really need to mount these to a metal or a plexiglass C.P.)
Concerning the 4-, 8-way story they are perfectly adjustable, but it's not practical, you have to loosen four screws at the bottom of the joystick, twist the plate(s) and fasten them again.
I bought an extra joystick to be a dedicated 4-way .
Most of the equipment is manufactured by Suzo (they only carry a few Wico items)
Note : If you want to order at Suzo you need a V.A.T. number (B.T.W. nummer), if you don't have one you can always ask a friend who has one and but let them ship to you.
If you want, I can mail you some pics of the joysticks and how I mounted them.
