I Made my own it only took a few minutes, find a steel car antenna that screws off, a peice of old broom handle for the handle. i drilled through the handle in the center, countersunk one side so the nut would be flush tightened it down and wrapped the handle with electrical tape, used side cutters to cut the little ball off the tip, and there you have it!!!
Hope this helps, Preditor[8D]
I bought mine at a insulator show for 10 bucks, its spring steel. I have been told that it is fairly cheap to go to a welding shop to get one. I guess it depends if you want spring steel, or not. Spring steel will be more expensive.
