Roger that.
I've had ONE truly high grade (Swiss made) 6" vernier caliper since 1969. It's a great tool and very rugged but I rarely use it anymore - the scale has gotten too fuzzy to easily see. SO, in '93 I bought a 6" Chinese dial caliper with the Midway name on it. Still have it, it's still accurate but ... the rack gear does collect gritty stuff and it's hard to keep it really clean.
After buying a South Bend metal lath in '95, I finally got a $12 Harbor Freight dial caliper just for my machining work; it is also Chinese. In fact, I later examined several other dial calipers that were branded by our common reloading makers and, no matter what name was on them or what they cost, every one was identical with my Midway and they all read dead on or within a half thou according to my precision "Jo" blocks. They work well and, IMHO, NO RELOADER is ever going to wear one out; I don't know what more I could expect if they were all Starretts!
Today, H.F. is getting about $15 for them (on sale) and, if the buyer is unhappy, he can make an exchange or immediately get his money back. (Try that with an auctioned eBay used tool or from a pawn shop!) And, the purchase risk is low; for the common price of one used pro caliper we can buy and toss a half dozen or so dial OR digital H.F.s before we break even on the used stuff! So far, YMMV, but after some 25 years of use, I am still quite happy with all of my modest collection of cheep Chinese calipers.
I normally sorta hate battery powered tools because the batteries tend to die. But, my two H.F. Chinese digitals - yeah, why not have two, they were very inexpensive! Digitals don't have exposed rack gears so they never get dirty and cranky to use. And extra batteries don't cost much. My best recommendation to reloaders (and home machining hobbyists) is to get a Harbor Freight digital inch/millimeter caliper.
NOTE: The only difficulty I've ever had maintaining zero in any precision caliper or micrometer is keeping the jaw faces very, very clean, otherwise I would just be measuring surface trash.
