I'll second on the Kobalt. I did that very thing and like it a lot. I've got a lot of older Craftsman tools and have bought a lot of Craftsman tools in the last year and a half, but wouldn't buy one of their torque wrenches. Matter of fact, their ratchets period are junk compared to the Kobalt ratchets at Lowes.
I have no experience with CDI or Tekton torque wrenches. I have a few other Tekton tools, seem fine. Looked at their torque wrench when I was in the market, but went with the Kobalt since I can just walk into the store and exchange it.
