The cheapest mess tin I know of is to go to FallApart or KameApart and buy a stainless steel dog dish of appropriate size. They are well made and durable, light, can be heated over stove or fire, and cost very little. With two you can make an effective dutch oven with some bulldog binder clips.
Other good kits are the traditional Boy Scout type mess kit, I'd get stainless rather than aluminum, but it's your choice. They're not very expensive at big box and sporting goods stores or online.
Military surplus mess kits are also good, inexpensive, but somewhat heavy. My preference is to the Swedish, Swiss and German style kits rather than the US GI kits. The USGI kit is mostly to eat off of, not much to cook with, while the European kits are intended for serious, comparatively, cooking. They are available on line and at various mil surp outlets and stores.
Hope that helps.
