This topic intrigued me, so I just weighed my cook system. Soda can (7.5 oz) capillary stove (which is also the pot stand), strip of recycled foil roasting pan wind shield, 7/8 fl oz recycled spring water bottle as fuel bottle, lighter and AL "Boy Scout" pot rescued from a thrift store for $1.99. 188 grams. Add a plastic cup and bowl and cozy and the whole boil, rehydrateand eat/drink set costs less than $5. Works well down to about 0C if you are aware of the limitations and proceed accordingly (keep fuel and stove warm, insulated from ground). Usually uses less than 30 ml of fuel for a meal & drink. Use Ethanol (denatured) and/or methanol as fuel - never isopropanol(except with a stove designed for it- Jon fong at Flat Cat makes one). Read the label on the container, it will tell you the contents, so that you get the correct fuel.

I still love my SVEA 123, but I don't take it backpacking.
