A good low-range torque wrench is expensive. My Sturtevant was $150. I am not sure I would trust the readings on a low-range torque wrench that was made to lesser standards, and certainly would not trust a big one in the lowest area of its range. 45 inch pounds is a pretty low amount and you need to get it right. I have a Thomson X2 on the cross bike and so far, no problems.
