Yes, I have a set plus extra odds and ends. Inherited from my father, who was a mechanic. I'm sure he picked them up at an auction, it seemed like we went to one just about every weekend. Unfortunately, I keep them in the same drawer as the 1/4 stuff, so it's always a chore to match things up. But this is the toolbox in the basement, and I rarely use stuff out of that box. There's also some 8 point sockets in the drawer. No idea where they're used.
And yes, the 9/32 size was on purpose to keep people from stealing them, but I guess if you get the whole set it doesn't matter much.
