$75 to calibrate a torque wrench?

FWIW I just used Angle Repair in West Virginia to repair an S-K 3/8 drive torque wrench.
They were listed as a repair/recalibration service and still were in business.
It also happens to be one of those listed by CDI (see link in Halifaxhop's post)
Hardest part was making up packing box to ship. Shipping cost more than the repair. They fixed it and only charged me for recalibrating. Total, including shipping both ways, was roughly $55.
Well worth it to me.
I liked that wrench and even though I bought a digital to replace it, wanted a click type to take to the autocrosses and as backup.
