You can make your own if you have enough BPC sets to tear up, that's what I did. Took the coil out of another set, wound it up in a 10" coil, then powered it with a transformer. You can't power it directly off the line, or you'll blow fuses. That's why I used a small step down transformer, I think it's like 18 volts at an amp.

Or you could wind enough wire to run it off line voltage, but it seems a safer idea to run it off lower voltage. Failing that, Ebay always seems to have some.
