Yeah, I have one and it is great. We gave one to our son as well. It makes a great present.
Look it up on Amazon. For not much more than a dinner out you can get one and stop worrying about how you will cook or heat water. As you say, it will burn about anything but thrives on small wood like branches you can scavenge and don't need to cut or spilt. The deluxe versions run around $129, but they are well made and should last forever.
I got mine from their actual website, StoveTec (first company that invented them), Eco Ceramic one for $102.95, free shipping.
No matter what happens, that stove will be here and work with twigs. I wrote about this stove on another website and a lady ordered one. She lives in a high rise and was so worrying about an emergency and not being able to boil water or cook. When she read what I wrote, she wrote back and said there were many bushes and small trees around that building, and she could gather them and have fuel. She is going to put the stove in her fireplace.
I looked that up for her to be sure it was okay for a fireplace, and found great big stoves like this are being stood by a fireplace with a hose going into the fireplace so the smoke, what little there is, goes up the chimney. These big stoves are being used to heat a room. There is no problem with this little stove sitting in the fireplace as long as the flu is open for the smoke.
