Sorry i haven't got one for sale but i would recommend the tototek adapters just a heads up they dont work all 6 buttons on street fighter you get 3 and 1 button to swop between kicks and punches but apart from that they are well woth it.
got mine connected to a converted dreamcast arcade stick with seimitsu LS-40 stick and seimitsu clear green butttons and have tototek adapters for saturn. TG16, megadrive and pc engine they work on 99% of games but you will find one or two that do odd things with then from not working at all to moving on there own.
