I ordered it from Amazon on youngest daughter's Prime account, and she handled the return and I shipped it out for about 80% credit yesterday. I think I just want to find my old OA Vaporizer unit and buy one of those plug in charging stations that Camaro 7 was talking about. Something easier than lugging a battery, and it is cheaper than a good truck battery. They have them at Harbor Freight, and I am familiar with their extended warranty, beats the daylights out of Home Depot's.
If I can't find it I think I want to build one rather than spend $80 for $10 worth of parts, if you can find me a plan Bob.
