There are numerable threads on what micrometers and calipers should be acquired. However, the majority of the responders are machinists stateing what the have bought and what they thought of the purchase.Unfortunately, Its all a discussion about name name brand or country of origin. What I want to know is what makes a B&S or Mitutoyo $100+ micrometer better than a $15 knock off? I mean, from a novice's view point, when starting out, does it really matter? What are the characteristics that determine the quality difference? What are the minimum qualities one should look for?
