FYI: Very seldom do I ever use a travel style indicator. Only when I need more range (travel). Most often I prefer to use a test indicator. Interapid make the best test indicators (just my opinion) and mostly are all we use. I do have Starrett, Brown & Sharpe, Mitutoyo and Federal brands as well as a couple cheap imports in my toolbox at work. These I have accumulated over 40 years in the Tool & Die trade. They all work well. It's mostly a matter of personal preference.
For working on our old trucks, I wouldn't be afraid to use a cheap import (test or travel style) as long as it repeated well.
