Kathmandu Arcus Gas Cooker

Wait for a store sale and it is one of the best value cookers around - I would rate it higher than many others that cost double or more. I've used it for about two to three years in a range of alpine and cold conditions and it lights and heats well although it does obviously need a wind shield
Lighter always works (after about two years of medium level use)
Light weight and packs down small - easily fits in a small billy with the fuel canister
Reasonably good fuel control
Very well priced when bought on one of their sales
Nil - very good all round
