I've also heard that clicker-type torque wrenches tend to go out of calibration or be out of spec in the first place. My suspicion is that a cheap, Harbor Freight unit would be more problematic in this regard than a more expensive unit.

I agree that parallax is an issue with beam-type wrenches, but these wrenches' simplicity and low price more than make up for this for me (as a hobbyist).
