As others have said, you can test the calibration using DIY instructions you can search for. There are also little digital torque boxes you can attach to measure the torque; they claim to be accurate within a few percent.

The 3/8" Dewalt ($100usd on Amazon) should be more than good enough then, I see motorcycle engine builders who hobby using a HarborFreight.
Will do a sanity check by getting a more traditional 3/8" deflecting beam torque wrench. Probably use that for the lower torque ranges and it's also useful for spark plugs.
