Get a Bernzomatic TS8000 and be done with it. It's $40 upfront (amazon), but it'll never fail you. Performance is fantastic, you can use cheap camping propane (like $2 for a pound that'll last you months) or step up a bit to MAP-PRO yellow cylinders which might have a less gassy flavor and they burn a bit hotter (like 100 degrees F or so, not too much hotter). They're highly adjustable, instantly start, have a lock to keep them on if you're doing multiples, and can be used for plumbing/garage stuff if you need it too. It's a proper tool, instead of a gimmick preying on the amateurs.
