If you want cheap get a beam torque wrench.
The only thing a click torque wrench has over the beam type is you can use them in tight locations; when straining on a wrench at a high torque it is easier to listen for a click than to look at a shaking gauge; and a thing called parallax distortion. That is just a sophisticated way of saying you need to look at the dial on a beam wrench straight on. Any angle off to the side will give you a false reading.
Remember that a torque wrench is only good between 20% and 100% of maximum setting. In other words if the maximum setting on your wrench is 100 ft lbs; it is only accurate between 20 and 100 ft lbs. I try to use a wrench size where I can stay in the 30 to 90 percent range.
