I agree on the Sears recommendation. I picked up a 1/4" drive unit that reads in inch-pounds. I think the 3/8" units that read in foot-pounds are overkill. 99% of the time you’d be working in their far lowest end, so the accuracy won’t be as good.
My 3/8" measures both ft-lbs and nm, but you’re probably right about it being a bit over the top because I am generally working on one end of the scale.
