The Zippyy cocktail (shorter shaft) style joystick is a great choice for a versatile, inexpensive joystick.  Easily adjustable between 2, 4, and 8 way. You can play the classics or the fighting games by simply shifting a plate on the bottom of the joystick. Combine this with and import top and you have a great joystick for only $10 !

The design of these joysticks is identical to the Seimitsu in sizing, there are a few parts made of different materials, ironically, the Zippyy has metal in many places the Seimitsu has plastic. The joystick handle on these is the short version and identical in length to the Seimitsu making it perfect for cocktail tables and metal control panels.

This is just a great all around work horse joystick, that can be adapted to perfectly suit games you want to play.

To allow for more ball top selection, ball tops now come separately and can be found here (Zippyy's used to come with 35mm import solid tops):
