Well my question would be how good of one do you want?
I sell a fair amount of used torque wrenches. I test them all against a digital one I have and results have been varied. Any well used torque wrench may be off regardless of brand but Snappy's tend to be closest. Cman's with the black plastic handle often test well and I normally get 35 to 40 for them.
I have had some KD's test well, often re branded.
Most of the truck brands that are fairly new test well.
I have also had the HF ones test good
So a lot depends on your budget and what you plan to do with it. If you are putting race motors together, buy a darn good one. If it is a less demanding application where even torque for all the bolts is most important and being close to the spec is good enough, then buy a lesser one or a used one.
Either way, if you are real picky about being as close as can be to a spec, then you need to have any torque wrench calibrated once a year anyway
