How hard are these to find by comparison to the Avenue pad? I have two of them. There are 2 turbo settings for all of the buttons, although for some reason buttons I/VI share the same setting. There are also 2 slow-mo settings, as well as the obvious buttons. I had never seen these until they were included in a lot I recently got from eBay. My understanding is that the only game to use the 6 buttons is Street Fighter 2, so I'll probably be selling these off shortly.

Thanks,
Drew
