I read a couple hundred for sale ads a day, and have for as long as I can remember. I see more filing cabinets and storage cabinets for sale now than ever before. I think we are in the golden era as far as a guy finding metal storage cabinets. There is an auction company warehouse near me that has several hundred units available at all times for sale, but there are other places on CL an hour away in the triangle area with better prices. Some lateral files have drawers. Some have doors that slide back and up into the cabinet, then have an open front drawer exposed for use. I like this type as they can be used as shelves or drawers, and can be hidden by pulling the doors down. This is the type I have in my shop.
