I have quite a few top boxes, although I tend to have to pay ~$50 apiece. I also have bought a lot of the Craftsman and similar style handyman's hand boxes. I clean them up and then sort tools etc. into them by job. e.g. I have one for batteries, one for soldering, one for air tools, etc. One of the Kennedy boxes holds stereo/turntable related stuff, the rest are mostly handyman tools that I need to sort better. I was never very good at organization and going through this has made my life infinitely better.
I also have two 26" Craftsman roll cabinets in my storage locker, one is mechanic's tools, one is again homeowner type stuff. Bought those new when they were blowing them out, I'd order them for store pickup because I still had local stores then.
