BTW, that Snap-on unit is of interesting construction. The old-fashioned "beam" torque wrenches were IMHO more rugged but also a pain to use because of their width and the gauge reading problems. Just guessing here, but this must use some kind of a miniature electronic load cell internally.
When the patent expires, it'll be at Sears for $99.95, and Harbor Frieght for $39.99...but I probably won't be doing this stuff by then!
