I've been experimenting around with the Brunton AF and it will boil water and run Alcohol with no problem. I've been side track lately but I plan on experimenting with a lot more different fuels other than car gas and diesel. The only bad thing I've experienced with this stove is that you need a lighter to fire it up. My old MSR stove I used a piezo electric grill spark to light it. Other than that, I'm going for propane next and see if I can blow my self up.
I don't know on the reliability of this stove yet, too new and few people I know of have got these. I need to also find out what it will do in extreme cold and how well it holds up maintenance wise. My old MSR is a jet engine, either boils water and burns food or it's off. Nothing much in between.
