Do you have a True Value hardware store near you? I think they still have a lifetime warranty on hand tools. Years ago I bought a bar-type torque wrench from my local store (Master Mechanic brand), broke it once, and it was replaced free of charge, no questions asked.
Others here would know more than me, but the impression I get is that the "click" type torque wrenches are more accurate than bar type?
If you are just planning on using the torque wrench for things like lug nuts, then a less expensive one will work fine. But.... if you think you might end up doing engine work with it or something similar, consider spending more money for a higher quality one.
