I can understand why a pro like Fred needs a top of the line box and tools. Daily use as a pro is different from the average Joe wrenching on his own stuff. I mainly bought USA made Craftsman tools & the rollaway stack, but also a smattering of both higher and lower quality tools, depending on the task.
Glen mentioned the snap-on line wrenches. Decades ago, I bought a set of Wright metric line wrenches, aka flare wrenches...fit and function, very similar to snap-on in my opinion. Price? About 1/3 less than Snap-on. Glad I bought them when I did. Tool prices today get almost scary to me, remembering what I paid long ago. Anyway, a tool line guys here might want to check out...very high quality industrial, made in Ohio for a long time. Still family owned, if I'm not mistaken.
