yes a electric grill ignitor is a little less expensive, but its doesnt give you 100,000 volts or more like a stungun
You won't get 100,000 volts with a stungun either. Those numbers are taken from what the circuit can theoretically put out with no load applied. Add a spark gap and it'll go way down.
If you can't jump a 3.5 inch gap with your stungun, it's not putting out 100kv.
Grill igniters, seventeen dollars at walmart. Appears to be designed for two gaps and comes with a battery.
