We use calipers at work everyday and the company provides our calipers for everyone's use. That being said I have been fond of the Brown and Sharpe dial calipers. They are well built and the tips for ID dimensions are sharpe so you can get in smaller holes to measure ID diameters. You have to be careful and not break the sharpe tips off. But I think they are well worth the money and if you know how to read calipers well i'd go with the dials, no batteries, no fuss, just straight forward mechanics and old school ways, lol. After using the Brown and Sharpes when you pick up a set of cheaper calipers you will feel the difference.
