Half-decent stormproof lighters are available from the Gadget Shop for about 4 quid.
In terms of waterproofing matches, I found that, if you don't wax/lacquer the whole match, if the end gets wet, the moisture moves up the matchstick as it's absorbed by the wood and the head gets wet. Either bite the bullet and buy stormproof matches (like the REI ones) or make sure you have a good waterproof container (film cannister? with a bit of cotton wool for tinder and to prevent matchheads rubbing together - also put half the matches opposite way round, like head-to-toe). The best idea, I suppose, is to have a few different ways of lighting fires, spread through your kit: matches, stormproof lighter, firestick, etc. Ie, don't put all of your eggs in one basket.
Cheers,
Mike
