I have some cheap Pittsburgh torque wrench that I purchased from Harbor Freight and Tools a few years back. I'm pretty sure it's no longer accurate (if it ever was) but I don't plan on calibrating it. I'll probably just get a new one. Like TypeSH, I use it for almost everything but I don't trust it for little things like internal engine work. I'll probably pick up a more accurate smaller torque wrench for that.

Mine is a 1/2" drive and measures 10-150ft-lbs. I just use a 1/2" - 3/8" adapter for using my usual sockets.
