I would not recommend the Harbor Freight torque wrench. Sometimes it clicks and sometimes it doesn't, causing you to overtighten the fastener. In fact, I'd go so far as to say that I won't trust any tools that come from Harbor Freight.
If you don't want to spend the money on a good quality click-type, then get the beam-type wrench. With those you can see exactly how much torque you are applying and you don't have to worry about overtightening.
Make sure that any torque wrench you buy is designed to handle the range of torques you need.
