I'm not sure where the comment on HF torque wrench accuracy comes from. Here is one test that provides a pretty favorable result:

I've seen others including a comparison to Snap on where they were not much different.

For ~$10, I think they are great. Also you have to consider the variability in the friction of the threaded fastener. What you really want is a certain stretch or stress in the fastener which provides a clamping force in the joint. But when you turn the fastener, the rotational force is resisted by friction which varies from fastener to fastener. That variation is far bigger than any inaccuracy in a HF torque wrench. Long way of saying the HF is plenty good enough.
