Awhile back I ordered a pair of J-Stiks from Ultimarc (each version).  My original understanding was that they were modelled after the Sanwa JLW-UM-8 and JLW-TM-8, respectively.  But I thought they were replicas, not originals.
Looking at the actual joysticks, I noticed they have the "Sanwa" name embossed in the various parts.  I realize that in itself doesn't prove anything, but are these legit Sanwa sticks?
