Whats the torque spec of the manifold?
Depends on how much money you want to spend, and how well you will be able to read a beam type if you were to use it.
Clickers really need to have the calibration checked every so often, even if you don't use them, they really need to be checked. Beam type, well, they are almost always accurate unless they have been abused and pulled past their limits.
¼" drive is horribly expensive, no matter what you go to. If your need for it is limited and it won't get used once a year or less, I would not waste the money on a clicker. (I have clickers, but I also bought them used and have access to a calibration room to have them checked).
