hey folks i picked up a freedom ace plus at a garage sale its all there but the plug is missing on the coil wire i put batterys in it and it powers up and costantly beeps i assume becuase the coil is unhooked, so do any of you have extra coil i can buy cheap or borrow dont really want to spend much unless i know if it works ok. and is this a descent machine is it worth spending a few bucks to fix it thanks hh
