>>I saw that shipping from Eydon was only a few pounds for international.<<
I noticed that too, and acted on it. Ordered a "Popular" last night, from far, far over the horizon, somewhat north of where the sun rises. We'll see how long it takes.
I'm sure I'll play with mine with a variety of fuels outside, but I confess I'm most curious about how well it does with Esbit tablets indoors for when the power's out.
Physics being what it is, though, I expect it's MUCH more efficient once the inside gets sooted up, which would probably take a long time with Esbit alone. In fact, the effect of blackening heat-transfer surfaces is often so dramatic that it might be worth a little stove paint in there...
