My GTA 1000 got in a wreck. Really the only thing that is good is the control head. The coil and battery pack is broke to pieces. Even the part on the shaft that the head slides on. So if you have a cheap non working G series machine with any old coil let me know. It would be any of the Green machines that have the slide off battery pack. Depending on how much the parts are I may just scrap it?
