I like the SS cup better than the TI since it fits tighter but it's heavier. I made a little support/stove ala the GI canteen cup, see pix. The stand is made from aluminum stovepipe cut to fit the cup exactly, the L-shaped supports are made from the SS strips you get from old windshield wiper blades. Packed up, it's not much bigger than the cup itself. For a lid, there's HD aluminum foil.

Edit: Hmm the second image doesn't preview in the post...anyone know how to get this to work? It's just a picture of the stand wrapped around the cup anyway.
