We charge $65 (this is in Canada), and are one of the more expensive places. I would expect to see a range of $35-$70, however to make matters more complicated there are lots of places that "calibrate" torque wrenches don't know what they're doing. I would quiz them on what standard they follow; they should say ASME B107.14. This requires using a mechanical loading device (pulling a wrench by hand allows you to produce whatever reading you want), and minimum of three test samples at each point. If they aren't able to quote this without prompting, move on to another lab. Make sure they will provide all readings as well.
As for which wrench to buy, how much to spend, it's a pretty mixed bag. There is garbage out there that is super cheap, and unfortunately some garbage that isn't even that cheap. Westward are just about the worst ones I've ever seen - not only do they almost never pass, just as often as not they can't even be made to pass. You might find a decent one for $100-$150, but there are so many brands and generic knockoffs it's hard to give specific advice. The older Craftsman wrenches are good; I can't comment on the newer ones as I haven't seen one come through our lab. Older Mastercraft are good, but newer (last 10 or so years) are absolute junk, especially the Maximum series. Snap-On, Proto, Mac Tools, Gray Tools, ATD Tools, CDI, Precision Instruments, Armstrong all make consistently decent stuff. Precision Instruments make an exact copy of the Snap-On TQ style split beam wrench for about half what Snap-On charges. Those are my favourite type to use. A caveat though is that they wear really quickly at first during a settling in period, so they absolutely need to be re-calibrated after a few thousand clicks; thereafter they are more stable than micrometer style wrenches.
