I am going to replace my old Sears torque wrench, am considering SK and was wondering of a flex head model is worth the premium on price, e.g. an SK 74251 1/2" 25-250 ft-lbs retails for about $83 and an SK 74256 flex head 1/2" 25-250 ft-lbs retails for about $137. It may be that other factors add to the price but I am unaware of them. How often is a flex head really handy and wouldn't using an extension work in most cases?
