I'd suggest you buy a few cheap torches. They are reliable, and when they crap out, you can toss them without having to deal with the BS of Colibri's "Customer Service" --which SUCKS by the way.
Out of the expensive lighters, nothing beats a Trifecta, but don't EVER drop it. The mechanisms inside are extremely fragile. (*which is why I suggest the cheap torches, they're durable and you can beat the **** out of them.)
As far as fuel goes, use ONLY Colibri for ALL your lighters. Vector SUCKS!! It has killed my Volcano lighter (which I loved) and has clogged up many of my other lighters. "Triple-refined" my ass! NEVER use Ronsol. You might as well use water. Ronsol sucks even worse than Vector.
Hope that helped.
