It definitely does use nuts & bolts to hold it together. The manufacturer (I'm not at all associated with him) just moved his production and the price dropped due to some improvements in the new location. I do not have a Bushbuddy Stove so I can't compare them, but they do seem to be quite similar. I wasn't sure if I wanted to bother with a wood burner but this was a relatively inexpensive way to give it a shot (I already had the 1L Pasta pot).
The stove comes with a base but it is not attached. I think it's the bottom of the can that's been removed with a side-cutting can opener. It fits perfectly and you simply set the stove on it.
The stove is super easy to use - I usually have a scrap of paper around (most often a piece of the map from the trail recently covered) so I ball that up and put it in on top of the grate at the bottom of the stove. I then fill it with small twigs roughly 2-3" long and no bigger than the diameter of a pencil and light it from the bottom with my lighter. I then put it down on the base, put the pot stand on while it catches, put my pot of water on, and start feeding the beast more twigs.
I haven't used it yet, but I did buy the alcohol stove that is now sold on the same website. What really seems to be nice about this is you can use a combination of alcohol and wood without worrying about messing up the stove (no jets to clog on the stove). I used an Esbit in the stove last May to get some really damp wood going and that worked pretty well, but I'll take the alcohol stove the next time.
I'm not sure what the return policy is if you don't like the stove, but for $32.95 (plus shipping) you're not risking much. It comes with a stuff sack and, as I mentioned earlier, fits beautifully inside the Evernew 1L Pasta Pot while it's in the stuff sack.
