If anyone here is a fan of Ultimarc's "J-Stik" but looking for a different color besides red give these guys a call. Ordered the black ball top sanwa and a couple of buttons. Recieved them in two days priority mail. Had a question before ordering and talked to the owner direct. Answered all my questions.
