Wera makes a nice one, around $100. Got mine from MSC. Occasionally on sale for $75. They make several torque 'drivers'. Mine is 'inch pounds', also. I never carry mine 'to the field' unless I've traveled a long distance (like out of state) and then I pack a small tool kit and it is left in camp (gunsmithing in the field isn't recommended).
I like Sears Craftsman.........never had a problem with mine. With any torque wrench.....after you are finished using it, back off the adjustment past "zero". Leaving tension on the spring will make it go out of calibration and you won't get an accurate reading.
