So I've been thinking of getting a Kelly Kettle or similar. Anyone on /out/ have experience with these?

I see that you can get an attachment to cook on top of it too. Does this actually work well? Can I use it for pretty much all of my hiking/camping cook needs? I'd probably just get the smallest size, since I will mostly use it on 1 or 2 night trips for just myself and maybe 1 other person.
