I use Vector's butane with my Dupont and haven't had any trouble with it. The Dupont needs a special adapter because it's designed only to fit their crazy expensive single-shot refills, but the cap of the Vector can includes a bunch of tips that I assume fit most standard lighters out there. I ordered the Vector cans from Amazon and they were eligible for the usual, free two-day Prime shipping, so special slow shipping doesn't appear to be a strict requirement.
