I heard ZIPPO and similar lighters weren't good to use for pipes because you can taste the lighter fluid used? Not sure if true or not, so I went on eBay and bought a BaoFa lighter that took butane.
Lighter is decent, doesn't light well if too close to the tobacco, need to light it then bring it closer. I managed to snag one off eBay for about $3 (Canadian) from a China seller with free shipping.... just under 3 weeks and was here. Been using it for about 2 months. Best part is that it has the tools built in. Amazon is like $30+, but again, watch eBay, shouldn't have to exceed $5 and it's a pretty decent lighter, and easy to refill.
My (belated) birthday gift a couple of weeks ago though, I got a Zippo lighter, just a regular one not the pipe one, PLUS I got a Thunderbird brand insert. Basically take the inside out of the Zippo and replaced it with a butane insert designed for pipes. Works really well, doesn't have the 'pipe hole' for the flame on both sides like the Zippo ones have but, doesn't affect me... maybe a lefty would find it cumbersome though. Nice thing though is, it fits any standard Zippo lighter, so, not stuck buying the Zippo Pipe Lighter which I think comes in maybe 3 options. Costs more (if not a gift) but looks good, works better... downside is no external access, have to pull the insert out to refill, and until wears in a bit, it's a bit tight.
Debated drilling a hole in the side of the Thunderbird to match more what the Zippo insert is like, but works so not going to bother. I may however, drill a hole in the bottom of the zippo for refill access.
