One option is to find the local freight companies in your area. A
friend told me that he goes to a monthly auction at a freight company.

seems if a package breaks, and they have no way to identify the
parts, they sell them at auction. I haven't looked at this but it is
a possible local source.

Also, check in the local paper for other auctions. you may find
something neat.

And don't forget yoru scrap yard.

Mine has a full height (6 foot) rack with clear plastic door. I
think he wants $100.00 for it. nothing inside and it's been in the
weather. He gets others that are pulled from old telco stuff.
