I have several CDI and Snap-On torque wrenches with 1/4" to 1/2" drives from a dial inch-pound to a couple several-hundred foot-pound clicker types. I have a KD-Tools clicker that I use on the road for wheels that I carry in the vehicle. I periodically check them all on a standard. I have found the KD-Tools wrench to be plenty accurate for my "on the road" uses and bought it at a swap meet. The CDI and Snap-On wrenches I picked up used on eBay and in pawn shops. I have no other experience with other brands.
