The ones I pick up from my local Dollar Store are called Jewel Strike (obviously a diamond rip off). Dirt cheap, but they seem to work. I normally light 2 at the same time, give it a few seconds to burn off the tip and light away.
That's the stuff! I tend to keep some of the little ones around, too - a small box fits nicely in my sporran. :DDiamond - Strike On Box Large Kitchen Matches 300 count.
