I went through three 10 dollar 1/2 torque wrenches, all from Taiwan, all off by as much as 20%. I got fed up, wasted a bunch of time rotating my dads tires, and purchased this:

Oddly enough, I also bought a spare $10 3/8 from taiwan, and it was spot on, all through the range..
They supply to SO. I have the 3/8 and love the durability and not having to store at lowest setting. Buy once and forget it. No way I would spend money on ICON when you can get USA made for around the same price!
