Now that I'm building fires more often away from my usual spot in the yard, I'm becoming more conscious of my surroundings when I build one. Therefore I'd like to invest in some sort of twig stove, for when the area I'm cooking in isn't the greatest for building an open fire. But I'm a bit lost on the stoves. What are the advantages and disadvantages of the different styles? I like the idea of the ones you can dismantle and store flat, but I'm open to any kind. Also, since they can be expensive, are there any "budget" ones that are decent, so I can try some styles before I settle on one?
