S-box or Neokey?
 

Hi, I'm thinking of buying a neokey for my PS2, but I recently came across 2 versions, one says "S-BOX" on the front of the little neokey and the other says plain "NEOKEY".
Does anyone know what's the difference if there is any? And which would work better with a NTSC PS2 v3.
Please excuse my ingnorance. Thanks.

the name on it is the only difference.
