we have a kelly kettle and a ghillie (same principle but better built and with a whistle! we take it with us when we go canoeing and camping. too bulky to cart on the bike. ive an aldi trangia clone too, a brilliant piece of kit and half the price of the real thing with no difference in performance, we also have several gas stoves, and they arent too good, jetboil is ok its quick and useful, but the problem with gas is the cold. ok modern blends are better, but when it gets below zero, you struggle to get the gas to evaporate in the can and you care constantly shaking it up to see if its empty. best stoves by far, are petrol powered ones though. especially on the bike, cos you need carry no spare fuel to cook with. we also have a coleman dual fuel which runs on unleaded which is the hottest burning of all the stoves we have. i have to say however that my fave of all is a small american fan assisted woodgas burner that we use from time to time when we go out travelling light, fan is charged with a small solar charger so never runs flat, and it burns wood and other solid fuel down to absolutely nothing with loads of heat, a flame like a gas burner and no smaoke at all. its a stunning piece of kit, though it wasnt cheap when i got it.
incidentally, if youve a panset, then look on youtube for 'penny stove' for a trangia style burner made from 2 old beercans and a stanlet knife. easily the cheapest stove out there!!
