Oh boy, I want one! Let me know when I can order one from you to put with the sensor kit you gave me at Dayton. I have it sitting here waiting for a use. I tried playing with it to see if I could come up with somthing useful, but I just too damn shitty of a programmer to do anything.
Any idea of reseller cost yet? I would love to put these on the site.
