I sill have a SVEA 123 that I bought back in the 60's !
It has been a very faithful companion and reliable product, from sea level to 10,000+ Ft in elevation.I have never had to rebuild it. I have ordered a pocket cooker from the backwoodsman website. I'm waiting for it so i can test it out. The day after I ordered it is when I found this site with info about the dakota stove so I will be trying that one out as well. I also use propane stoves but those I limit to vehicle camping.
