I prefer the Starret . Like AXX I have had it for 30 years. I bought 2 from "Harbor Freight" for my reloading bench. These have been great inexpensive devices. I have checked them against my Starret no problem. These are digital and mechanical read outs.
I agree that you don't have to spend a lot to get a good tool. I have several inexpensive digital calipers knocking around but my go-to one is an Etalon dial indicating vernier caliper. I forget how much it cost me some 30 years ago but it has outlasted the inexpensive ones (maybe because I am more careful with it).
Digital calipers are also better IMO because you can switch from mm to in. with a press of the button as well as zero it anywhere for different applications. Can't go wrong with that for the money.
Though I have a couple of fairly expensive ones, they are not needed for reloading. The $10 Harbor Freight digital ones would likely serve you fine. You can re-zero them at any time with a push of a button.
Just walking on the edge of of my grave.
