I've had several of the Colibri lighters over the years, one that I bought and three or four that I received as "smoker's rewards" (smoke so many cigarettes, send-in and redeem coupons, receive gift/prize). They have all developed "ignition problems" and I have given up on them. It'd be great if containers of butane were labeled with something like "Clean enough for a Colibri lighter!" but they aren't labeled that way. Personally, I've decided that the "problem" with Colibri lighters is with the lighter itself, as I kept getting "ignition problems" no matter which brand of butane I used to refill them, or how much it cost.
I prefer to follow the K.I.S.S. (Keep It Simple, Stupid) principle. If any of my Zippos won't ignite, the biggest problem is a lack of fuel, the next being that it needs a new flint. I couldn't fix a Colibri on my own, but I can get my Zippos up and running within minutes without sending them off, probably for weeks, for someone else to fix. My backup lighter is one of the ubiquitous Bics.
If you simply want a reliable lighter/fire source, a Zippo or a Bic will fill the bill without any of the "gee whiz" factor, and probably for a fraction of the cost. While I think it's cool that a lighter can melt a penny, I've never been in any emergency situation where melting a penny was a high priority. I guess that one of the blowtorch-like lighters could be used for limited welding, but, because I don't know how to weld, it isn't something that I require in a lighter.
If you decide to get a Zippo, the best way to fight the lighter fluid evaporation problem is to simply pack your Zippo with a bottle of lighter fluid and fill it when you need it. My Zippo always works unless it's empty of fuel, and it can be refilled with a simple 10-second squeeze on a lighter fluid bottle (or else it's too full, and can leak and cause a chemical burn to skin...).
Just my 2-cents' worth,
