Whoa!
A torque wrench is a tool that you will use throughout the build and for a long time after. I would only buy a HF torque wrench if you plan on using it for a pry bar, because I guarantee you that it will not be calibrated, and even if it is, it will not stay that way for long!
I would start with a Craftsman wrench as a minimum standard. No matter what brand you buy, take it for a calibration check before using it.Then after you use it for a while, have it calibrated again, especially if you drop it a few times, or use it to break bolts loose.
Good luck!
