Try Bugatti B-1001 on CBid for around $15. Always lights, has a punch, and two flames in a pyramid.

I can confirm that the Bugatti insert fits inside a zippo. I'm running 3 zippos with butane inserts (1 is a soft flame insert).
As an cold weather smoker, I can confirm that butane will not light if it gets too cold. To combat this, I keep my lighter in my pants pocket so it's against my body and then I don't have any trouble with em lighting.
