Propane and Stun gun

[Shrimphead]

Three Questions:
1.How much it would cost to build a direct propane injection system?
2.I've seen stun gun plans before, can anyone post a diagram or link to one? (I've searched but can't find it)
3.Would it be cheaper to build my own stun gun, or to get it off of ebay?

Bump, bump, bump.

1. it cost me $9 in parts from the store and $4 for a torch head from the local flea market. you dont really need a regulator
2. use a coil from a car and wire a couple of capasitors to it. charge them with a couple 9 volt batteries.
3. it would be cheaper to just buy one from ebay or a store because they are difficult to make. you would most defenitivly shock yourself at least once

Does it work as well without a regulator? My problem is that I don't really understand how a normal propane injection system is setup. I've researched but I still don't quite get it.
