When I lived in California, my workbench was a crude thing consisting of a piece of plywood placed atop a smaller table and a black plastic 15-gallon nursery pot; the kind used for selling young trees. It was actually a combination workbench/dining room table/typing table. Modeling equipment was kept in drawers or later, a fishing tackle box.
When I moved to Arizona, my roommate (who stayed behind) gave me the piece of furniture from the bedroom that he had a lot of his stuff on. Once settled into my new apartment, I screwed the plywood down onto his furniture, set up a different set of drawers and I had a new workbench. Over the 2 1/2 years I've lived here, my workbench has undergone tweaking and adjusting that still continues to this day, but it's certainly a lot more efficient than it was in California! Unfortunately, I have no digital camera or photo scanner, so I can't show you, but it works pretty well.
I also have a small workbench outside my door for the times when it's warm enough to model outside but not too warm. (Right now, it's definitely not good modeling-outside weather here in Phoenix; today's high was 110 degrees and tomorrow it's supposed to hit 112.) I also now have a separate set of tools, plus little divided containers perfect for holding subassemblies, spare parts, etc. that all fit into a large ice chest so I can now take my modeling on the road!
