Quick question: If I bought a good quality used torque wrench off ebay or some such site, should I be concerned with how accurate the tool is? Do these tools have a problem with needing to be calibrated on a regular basis? And if so, what is involved? For instance, would a snap-on TQR-250 that was a few years old typically need some servicing by a qualified person? I would love to save money over buying new but want to make sure I know what to expect. All advice appreciated!
