There are some serious tools and tools collections on this thread. I'm jealous. On the other end of the spectrum, looking back at my work this year I would have loved to have had a set of closed ended ratcheting wrenches. Maybe for the holidays!
The best ones I've had came from SK tools, however they don't seem to make them anymore. I got a full set from 10-19mm many years ago. They are ratcheting at both ends, each one two sizes - 10-12, 11-13, 14-15, 16-18, 17-19. They are slightly longer than others I've seen, and better weighted (not heavy)
