Hey I found this link on slashdot this morning - build your own extension tube! The article touts it as "building your own macro lens", but we all know better.

He uses a pringle tube attached to a body cover (with a hole cut in it) to fasten it onto the camera; then uses some cloth wrapped around his EF 50mm/1.8 to ensure a snug fit at the other end.
Seems to work ok... I think the only difficulty he faced was that the lining of the pringles tube is silver, which causes some light reflections...
