You just have to make sure to zero it out after you use it. The Snap-On PI style don't have to be zeroed out. If you use it quite a bit or drop them ocasional calibration should be done. When it comes to cost and accuracy it's still hard to beat a 29 dollar Craftsman beam style torque wrench. Never has to be calibrate, will be as accurate 50 years from now as it is today. It's biggest downfall is you have to be able to see the scale. Back when I used a beam style in the 60's I put a clothes pin on the scale where the torque topped out for what I was doing the needle hit the clothes pin and I knew where it was so I didn't have look directly at the scale.
Are there any downsides to a click style as opposed to a beam or dial style one?
Do they make the equivelant wrench in a 1/4 drive? I'm looking for a quality torque wrench that will go down to about 5 ft/lbs. I didn't see one on that website.
If you have a need to measure running, rotational, or breakaway torque, you cannot do it with a clicker. If all you are doing is torquing bolts and nuts, then clickers are fine.
For the average Joe homeowner, car fiddler/fixer, GJ type, probably the best choice is the Precision Instruments split beam 3/8 drive and 1/2 drive flex heads. They work well, are accurate, click so they are easy to use, and by nature, like an old beam type don't lose their calibration easily, and are forgiving as you don't have to remember to "zero" the torque setting to min torque after use, plus the flex head will make work much easier, and the price is right.
Precision Instruments 3/8 drive split beam 20 - 100 ft lbs
Precision Instruments 1/2 drive split beam 40-250 ft lbs
These keep getting cheaper, I paid $115 for the 3/8 dr from TT and $152 on the 1/2 dr, and that was a couple of years ago.

and most fasteners on a car are between 20-100. Below that you can use the German tightening method "gudentight" by feel.
Pardon my ignorance, but what type of situation would require you to know the running, rotational, or break away torque?
That is how people manage to F-up aluminum cylinder heads, and valve bodies...
Realistically though, I doubt to many home mechanics are messing with their valve bodies, but I'm sure there are some.
I'm an aircraft mechanic by trade, and in that business, we quite frequently have to measure force required to rotate some component (such as the control yokes during a flight control test) or amount of friction a self locking nut generates (then add the required torque to that to get the proper torque of the nut), or as noted, setting up auto and truck differentials would require such to measure bearing preload or friction. Not a lot of uses in the auto world, but they are there.

Someone who is replacing the head is going to know to use a torque wrench...plus it was a freaking joke...get it "gudentight"...German method? I thought it was funny.

I heard at one time that the Snap On torque wrenches are actually made by CDI Torque products. Is there any truth to that?

The similar CDI wrench is like half the price.
I purchased 2 CDI wrenches off E-bay and their great. I really like the solid metal handle and they are really smooth and easy to use. As others have said you just need to make sure you set them to their lowest setting before storage.
My experience with CDI was the same. The manufacturing plant that I interned at this past summer used a lot of CDI and Proto torque wrenches and I found that even after months of abuse, they still held up pretty well. I especially like the all metal construction of the handles.

I have been told not to set to zero on a clicker type torque wrench when not in use by the Snap On dealer down the road in my area including my Matco dealer.You set them down to the lowest number for a reason.Will ruin the clicker mechanism when set to zero.I have a Matco which has held up so far and is about 3 monthes old.
So what kind of torque wrench is appropriate for measuring rotational torque?

So you have to try to watch the needle deflect while you're slowly turning the whole assembly around? How do you ever stay lined-up rightside up and without parallax?
The only issue I had with the PI split beams is that the new ones have the plastic grips on the handles. This was done to save a production step of resizing the rectangular tubing to a round shape at the handgrip. The body of the torque wrench is made of a rectangular tubing and by using the plastic grip (which has to be cheap) it saves a metal working step. I did call and complain to PI about this, got the "everyone we asked wanted a more ergonomic handle grip" and I told them I wanted a more durable one, that a round grip was plenty ergonomic for me.
