If you are gonna spend the money for a decent pair of digital readout calipers, buy the Mitutoyo.
None of the reloading supply houses make digital calipers.. they buy them and have them labeled with the house brand.
The same is true of dial calipers. The made-in-China cheapies are functional, but if you want to get something that will last for a couple lifetimes, get the a michinist-quality measuring tool, not some plastic toy that will never be accurate.
Enco, Grizzly, and many other mail-order machinists' supply houses will have what you need.
