If the goal is to torque the bolts uniformly, buy what ever is cheap and in stock at HF or the local store. If the actual torque value is critical (engine rebuilds) I might still use the cheap torque wrench but I have picked up a few more expensive ones over the years for critical work, and they do not get used for non-critical work. You might be surprised at how much more important consistency is instead of a perfect torque.
From the way to long class I had in the military decades ago most people use the wrench incorrectly and get uneven/inaccurate results anyways. We found that we had a variation of over 50% when we tried to test. After calming down and being consistent we closed that gap. A few items such as always zeroing out the tench, pulling squarely with the wrench using the same grip, not jerking, only using the middle 50% of the wrenches range and a few more items make more difference that people realize
