My Zone VI modified Pentax spot meter still works perfectly after 20 years of dropping it off cliffs, smashing it into walls, denting it, breaking the dial off the side of it and leaving it out overnight in the snow. I still use my Zone VI 8x10 contact printing frame to make all my prints. I sold my Zone VI tripod a while back and replaced it with a Ries. While the Ries is lighter and fits my photographing style better in use, the Zone VI is a lot more rugged. I liked his stuff so much that I easily forgave him those prints (which, really Bob, were not that bad - They just weren't fine).
