The Kobalt torque wrenches are not made in the USA. But I'm not saying they're not a good torque wrench.
The Husky wrenches recently switched to USA made because they're now made by Apex and are identical to the USA-made Gearwrench wrenches. They're also very similar to Matco, Armstrong and probably others. More info here:

Just be careful that you don't buy a torque wrench that's too big for many of your jobs. For example, I don't even own a torque wrench that goes to 250 ft-lbs, and I have four or five wrenches. My most used torque wrenches are 3/8" drives.
For example, that Armstrong you linked to claims to go from 25-250 ft-lbs, but I bet if you were to buy it and read the instructions they would say it's only accurate from 20-100% of scale (50-250 ft-lbs).
So, keep that in mind. Many torque wrenches are only considered accurate from 20-100% of scale. The Armstrong you listed would be useless for a lot of underhood jobs, torquing drain plugs and other things like that.
