Same exact buttons. Shawn from FXButtons.com is the guy that convinced the manufacturer (an Italian company called Industrias Lorenzo) to start making the things in the first place. I.L. also manufactures Happ's regular buttons, as well as their joysticks, and the buttons and joys sold by several other arcade distributors. They do not have an exclusive license with Shawn, and so they make the buttons available to Happ as well. People with contact trouble might also try PMing Shawn here, his username is Shawnzilla.
