You will need a second 3/8" or 1/2" drive wrench for bottom brackets, cassette lockrings and the like due to the higher torques required. I have had good luck with the Harbor Freight click type; I have checked the calibration at work and the ones I have are well within the 4% spec. Just be certain that the one you choose clicks in both directions for left-hand BB and pedal threads, some only work clockwise. This is not an issue with the beam types or most higher-end wrenches.
