I think it's easier to just build a simple 1 transistor power oscillator 
on perfboard with a couple stages of multiplication and hand-wind a 
little inductor than try to futz around with an "eBay Special" tazer 
circuit designed to make over 60kV into doing what I wanted. Could 
probably have finished it in the time we spent talking about it; 
certainly long before a package from China arrived.

YMMV
