This is a repost from 2011, but my setup hasn't changed.
I use an Imusa aluminum mug from Fiesta market. It doesn't come with a lid and I looked and looked for one that fit. I never found one, so I pounded one out from a piece of flat aluminum. Also, the handle tended to get super hot, so I removed it and left just enough of a nub to attach a removable handle made from bicycle spokes. It's a light-weight setup that cost me $4.00 for the pot and wooden knob. (I had the spokes and sheet of aluminum laying around my shop - that would probably add another $6.00 to the cost.) The windscreen, stove, pot-stand and spoke-handle all fit inside the mug.
