Anybody have a good source for the least expensive set of flat files? I would like to make a long wall of drawers, and it will likely require a stack of 2 or 3 wide, each stack containing 2 drawer sets on top of each other. In other words 4 or 6 units. I would love to save some cash if I can do so. My carpenter friend is going to make a formics countertop to go across all of them for a smooth surface to stage prints for matting or display. I just expanded my office space to about 1,000 square feet, and I finally have the storage space to do what want.
