I've actually amassed a decent collection of lighters and knowledge about new and vintage ones recently. If we're limiting it to new butane lighters, there are actually a lot of misconceptions out there. Many of the popular brands aren't as good as you'd think; Colibri used to be good, for instance, but now it's one of the worst. The $500 S.T. Duponts or Dunhills offer no advantage in reliability compared to some cheaper brands. But as a general rule, go for soft-flame, flint lighters when you can. Piezo torch lighters WILL break, the difference in quality just accounts for how long it takes for this to happen. For torches the best are Blazer and Xikar (Xikar also has a lifetime guarantee). You could also get a bunch of cheap Ronson Jetlites and just replace them as they break. For soft-flame flint butane lighters, I can't recommend IM Corona enough. They are very high quality Japanese-made lighters, and are more reliable than any other butane lighter being made today (yes, more reliable than the $500 ones). I have two Double Coronas, which are intended for cigars (they have two nozzles that produce a wider flame). Very nicely made from solid brass with various platings, compact but has capacity, the flame size can be adjusted easily with a little flip-up knob on the bottom, and it has a lifetime warranty. They come with special carbon filters to prevent clogging, but you should still use at least triple filtered butane with any nice butane lighter. Prices are at most about $200 from dealers, but you can find them much more cheaply on ebay. They aren't as well-known, so you can get good deals from sellers, or if you wait around for an auction you can get a great deal. I got the gold-plated DC, which appears to be the most expensive model they have, for about $50 NIB. I have lighters with all kinds of interesting mechanisms, some from as far back as the 1920's. But out of all my lighters, the IM's are the only ones I've been using lately.
