I have to limit myself when I go there. I saw a lovely rack-mount WWV receiver that I wanted to take home, but I thought "What would I use it for?" I did end up dragging home an HP3440 Nixie DVM, but that's because I need parts to keep my other ones going. The guy said "It works," but you could tell it didn't. Still came up and almost worked, a testament to the engineering of Old White Men in White Shirts and Black Ties.
