I love cast iron ... but if it is for camping there are a couple of things to consider: (1) are you going to hike in with it or just drive up to your campsite, and (2) what is your heat source? If you can have an open camp fire then cast iron will be great - but if you're using a propane stove - you'll want something that heats faster - like aluminum or enameled steel.
