Search the forum archives, there was a guy talking about how he'd found a crate of them for sale at some show, something like 1.50 each. I'm not sure they were complete with burner, but a lot of people seem to replace the military burner with a civvy one. The civvy ones bloom quicker and usually have a flame adjuster, which the military one lacks because they're really intended just for boiing rat packs and brews. I made one for mine from the lid of a baked bean can.
With you on the stainless, if you aren't carrying it around the weight's no bother. I keep a stainless scouring pad in mine and since it's stainless in stainless there are no galvanic corrosion problems that way. I don't have any problem with burning food in mine although the heat does tend to get a bit fierce in the middle. You need to cook something that you can stir, and then stir it. I like anything with rice, cous-cous, dried powdered potato, cans of small or chopped vegetables, corned beef and some spicy seasoning which can all sit in a crate with the cooker and a couple of two-litre bottles of water. Zero maintenance for literally years. The 'use by' dates on corned beef are typically four or five years from purchase, vegetables often a bit less but I don't mind eating them two or three years past their dates. Give 'em a sniff first.
Most of the military surplus places have them for about a tenner. There are several other different varieties along the same lines from different forces, any of them will do the job. Some of them come with a little bottle for meths, some even come with a little cup. I haven't got one of the cups but they look on the small side for me.
