Tools Tested channel on youtube has some good videos on torque wrenches. He has a CDI/Snap On torque tester and has tested a bunch of wrenches. I needed a 1/4 torque wrench to install some small plugs on a HPOP and after watching his video I didn't have any qualms about using the $18 HF Pittsburgh...the clicks are not very audible on the 1/4 one but you can easily feel it break. Watched another of his videos the other day and plan on picking up the Icon 1/2 inch split beam here in the near future.
