There's only one version of the JLF. The only differences you will see online are ones that come with different mounting plates or wiring harnesses.
For your cab you will probably want this one:

A little bit of information about the JLF
-It is the same joystick to be found on official Street Fighter IV cabinets
-It is the same joystick to be found on official Virtua Fighter and Tekken cabinets in Japan and is becoming very popular in the US.
-It is the same joystick to be found in the Madcatz Tournament Edition joysticks.
-It is generally considered to be the #1 competition level joystick for all fighting games.
-It can be switched to 4-way mode by removing the restrictor plate and twisting it into a diamond shape. This takes about 1 minute if you have access to the interior of the cab.
The alternative to the JLF is the Seimitsu LS-32. It is known to be a little tighter and have a shorter throw. It might also be worth looking into if you want a more retro feel while preserving a great 8-way stick.
I guarantee that you will be extremely pleased with either stick.
