This brings up the issue of technological obsolescence. There must be a dozen stoves on the market which are lighter, hotter, and cheaper than the Borde which was a hot stove (what else?) in its day. Don't get me wrong, I carried a Borde and it proved crucial in a really rough unplanned bivouac in the snow many years ago - it is probably the reason I have all my fingers and toes today. If it works for your situation, great. I don't mean to dis your choice of stoves.

The Borde went off the market because it tended to morph into a bottle rocket if overheated. Mine died when the fill plug blew out. I replaced it with a Primus which served for many years and is now a souvenir above my desk - it still works, if needed. Nowadays I use either alcohol or a Pocket Rocket.

$100 on Ebay? I think I paid less than $10 for mine (1962). As a starving student, I watched pennies.
