lots of wrenches available new and used but used ones would need some sort of calibration check. Grease in the clickers can harden to where they no longer work, need disassembly, clean, re-grease and a calibration re-check. I suspect that torque wrenches are personal. I had a Utica 30-250 ft lb one that served me well for over 40 years. It was wearing out and needed another servicing so I donated it to Goodwill and replaced it with a new Proto one. The inexpensive Craftsman one I have had the plastic lockring wear out, and the part was not available anymore. It was good otherwise and accurate. Fortunately, TeamTorque had a new old stock handle and lockring for one so they fixed it and checked the calibration with the others I sent. They gave me a heck of a deal on all the service. They had serviced the Utica one perfectly when other companies just walked away from it. All it needed was a re-grease. They use a silicone based grease and it lasts a long time between services. In the end, I am willing to bet most people here, regardless where they got them, would not trade their torque wrenches although they might acquire a new one to them, new or used.
