All very nice set ups. I get asked all the time about the "right set-up" for my reloading customers and I tell them to find something study, give yourself enough room and try to keep it organized. I've got customers who have everything from a garage "man cave", rolling work carts, c-clamped in place single stage presses to entire rooms dedicated to reloading.
One my first benches was made of 2x4's and some plywood I put together using a jigsaw and a hammer.
Hopefully some more folks will post more pics, its neat to see all the different set-ups.
