I agree with Kroll on the wood floor idea. I came up in shops with wood block floors, as I'm sure many others here have. These new shops have those pretty epoxied concrete floors. if I drop a tool, it's usually trash' with the wood floor, you just pick the tool up and brush it off. Also, the wood flour is so much nicer to your back and knees. the only drawback to wood block floors, they don't like moisture. one little leak in the ceiling, and the floor stands up like a 2 foot tall pimple.
