Some of the Pepsi can alcohol stove crowd use stainless steel canisters to cook in. You can find them in WalMart, Target, etc. made for storing things from toothbrushes to kitchen spatulas. Just about any stainless steel container would work well for cooking. A lot better than uncoated aluminum like the Walmart grease pot. Don't use a double-walled or insulated container. Drill two holes and you can make a decent handle from a coat hanger or other wire.
