My torque wrench was calibrated by Caltech physicists to be balls-on
accurate.
(Line from "My Cousin Vinnie.")
And don't forget, you want to reach the prescribed torque while you're
turning the wrench, so the click-type ones are probably easier to use
than the bar-pointer type. I recently bought a Craftsman click-type,
probably the size up from the Craftsman one Jim described (this one is
10-75 ft-lbs). A little light for the axles and swingarm, but good for
most other stuff. Haven't had the accuracy checked, though. That
Snap-On one probably has a better range for the bike, since it'll give
you a little more headroom on the big bolts. These kinds of torque
wrenches are most accurate away from the ends of the scale.
