Why indeed…
I have to say that after trying to build one, and seeing how capable those little 3W torches are, I’m coming down on the buying rather than building side of the argument too. I’m definitely going to get my hands on some of the Ultrafire units – my friend is in Hong Kong this week so I’ll have him scout around for some cheap ones. If he can find enough, maybe we’ll even offer them out as compo prizes…
