By Craftsman 1/2" and 3/8" beam style torque wrenches from Sears, and you'll never have to worry about calibration.
The typical home user will never need the speed afforded by a click or electronic torque wrench.

That's entirely untrue. All torque wrenches can lose calibration. With high daily use ours are mostly beam are calibrated every 6 months.
80% is a very good number for the max accuracy. I have beam style. I've broken more than one bolt due to a clicker failing.
