I have dealt with them before. I purchased one of their spinners off of eBay and also ordered the optional aluminum knob. The website that is up now is a new design for them. All of their links did worka few months ago. They sell their spinners on eBay all of the time. I tested the spinner and played some championship sprint, tempest, and arkanoid. The spinner will get you by and has a nice usb interface (good spinner for $26). However if you ar a fan of tempest, etc this is not a great solution as it doesnt have a very good spin time and has very little resistance (almost spins too easy).
Hope this helps,
