I have two of these. Mitutoyo has a very strong reputation among professional machinists for accuracy and durability. This caliper is in an entirely different league from the more common copies that sell for a fraction of the price, several of which I've also had. It's worth every extra penny that you'll pay for it.
Digital calipers are under $10 on Amazon (but reliability may be "iffy"), or $20 for a much better one at Harbor Freight. The HF is a copy of the Mitutoyo Absolute Digimatic ($125). Very handy tools for a lot of things. Examples; nut width, string spacing, fret height and measuring the thickness of old credit cards to be used as gap gauges.
My 'toyo has well over a decade of shop use and still works great.
