Stay away from cheap ones if you want repeatability.

I was a machinist for many years and Sturvin says it well. I am personally a little more partial to Mitutoyo, but quality wise Starrett and Mit's are top-shelf. Used tools from a machinist are probably good. We may get mad and throw a hammer across the shop one minute and the next seen treating our dial calipers like the most valuable thing on Earth.
Some other guys have mentioned the cheepie brands and generally for a one-off use kinda thing they would likely be ok if you have the ability to test and confirm their accuracy through the range. However, I would not use them for machining close tolerance parts no matter what.
