I did this:

I used 30 guage kanthal wire, 10 wraps, and some sterile cotton balls from CVS. I think (not sure) it came out to 2 ohms, or around that. My ohm meter sucks.
I also used a helping hands magnifying glass with LED light from Harbor Freight so I could really see up close so make sure nothing was touching in the head.
I used a 5/64ths drill bit from Home Depot to wrap the wire, and then heated it up with my (now) lonely cig lighter. Then I tried as best as I could to squish the coils together to fit them into my Protank II mini's head.
I *might* use the silicon gasket on top next time, since when I lay my vape on its side, it likes to gurgle a bit.
But it works, and the flavor is ok for now.
