I bought a lot of parts on Ebay over the last year and generally saved for other material. I decided to lease the space with my wife and kids and sort of split it up between clean and dirty areas. We had to frame out space into a large existing multilevel warehouse.
We scored big time in other ways by leasing the space. The owner of the building co-owns a hair blending company that makes custom blends for brooms, brushes, etc. and happened to be getting rid of some old machines. These machines contained a plethura of 80/20 aluminum, PLC's, linear motion components, motors, gears, pneumatic devices and controls etc. I was able to augment and drastically improve the machine by using these materials.
Here are some photos of the raw material
