Well spotted Sweep, I hadn't noticed the extra cost of that filler adaptor, though agree it would be handy to be able utilise the stove gas on a long trip. But if you're cooking on a meths Trangia, why would you be carrying a gas cylinder?
Those cheap & cheerful pipe lighters on Ebay are specified as "soft flame" lighters & will likely produce a flame which rises back towards your fingers when inverted unless, as meic pointed out, you're sucking through the other end of a tobacco pipe you're trying to light.
A "hard" flame (blowtorch type) lighter (which can apparently burn & wreck your pipe) has a much stronger flame which holds its shape in the direction in which it's pointed. To me, that seems the way to go, for meths stoves at least.
I may have been inadvertently fortunate with my IMCO pipe lighter which falls somewhere between hard & soft flame types and think I'll be investing in a spare from Ebay before they disappear completely.
FWIW in the last 10 years I've done most of my camping between October and April and have been let down by most of the suggested methods of igniting meths at one time or another, inevitably resulting in me resorting to the trusty IMCO.
That said I've nothing but admiration for anyone with the confidence to rely completely on a fire steel for lighting meths in cold weather.
'Strewth, I'm sounding like a pipe-smoking, meths user - better sign out.....
