$80 includes shipping.  Awesome little titanium Sierra Zip stove.  It weighs only 9 oz and uses biofuel such as twigs, sticks, or anything else that burns for fuel so no more carrying fuel.  This is actually a prototype of the actual titanium version so it's one of a kind, but it has worked just fine for me the couple times that I have used it.  Battery will run for 8 hours and will boil water in 4.5 minutes.  This baby gets hot!  Great for the backcountry chef. Absolutely nothing wrong with it, the blackness is only soot that will come off with a good scrubbing.  Definitely better than any other wood stove I have ever used.  Only selling because I am looking to try alcohol stoves now.  Contact me at two six two - 288 - 15 eight 7   or email [email protected]
