the beam type wrenches are good for certain things, the advantage of them is they basically never go out of calibration, I'm talking about a good one not a china special, the clicker are good when you can't see the top of a beam wrench, they both have their uses, if you've had one for a long time you need to send it off for calibration once in a great while.

If you want a good torque wrench and can't afford a snap on, look for armstrong tools, I have one myself and I used it for years, it also needs to be calibrated then I'll use it again. They are US made and excellent tools, well worth the investment
