Ed, I just put this note out to reach anyone who may own one of the scooters built by our project. There are others out there who work on the rest of the scooters. Mako scooters are easy - they have dealers. AUL does their scooters, and I assume the same for Farallon. The rest I do not know about. WADR, tank mounted scooters are not "tec" gear - they should be sold at carnivals by the Bearded Lady , at best.
