My dad, who is a certified diesel mechanic says his torque wrench of choice is in his wrist. He can tell by the clicks in his wrist when tightening something when it's good. He's the only one who has a HF torque wrench. All the other guys in the shop have expensive ones. He went with HF because Most of the guys hardly ever use them and he's only used his once. I then asked him, "What happens as me the customer is told by you the mechanic that whoever changed my oil the last time stripped the threads on the oil pan." "When I the customer know that it was not stripped because I changed my oil and never over tighten." He gave me this look...

... and said that guys like that at the shop don't last very long. I am a craftsman snob and will buy the $70 one when I find the funds and it will probably sit in my tool cabinet being used only once and my dad will tease me about it. Oh well....
I to use my "calibrated" arm but when rebuilding engines,trannies,transfers,and diffs I use a torque wrench because if you don't torque to specs it could cause early failure.I have 3 torque wrenches,one 1/2" drive craftsman(normal uses),one 1/2" drive snap-on(precise uses),and one 3/8" drive snap-on(precise uses).I also check the calibration on them when ever I can(back in SD the snap-on guy does it for free).Again this type of tool is a "you get what you pay for" tool,yes many will not need those high price ones for the once a year uses but at least get a quaility one.It's sad the even the US military buy's crappy torque wrench's so that's why I use my own and I have never had a engine,tranny,or diff go bad that I have rebuilt due to under/over torqueing of fasteners.Just my 2 cents though.
