I can recommend the stainless steel 16 oz cup that fits on the bottom of a nalgene bottle - less than $10, fold out handles, cooks a cup of soup just fine. Looks like this - http://www.campbound.com/Stainless-Steel-Bottle-Cup.aspx. Whenever I carry a nalgene, I have one of these on the bottom of it.
