So, I finally broke down and ordered an AlphaFire 1Q. http://amzn.com/B00E3NTSAS I also ordered a 6v automotive relay that can handle 16v at 40 amps across the contacts. One AlphaFire, one relay, one ATV battery, some wire, few spade connectors, and some 'gator clips. Should fire darn near anything. It's on the slow boat from China, but I hope to have it in a couple weeks. Anyone else use one of these guys?
