Harbor Freight/Chinese Calipers
Don't know how I ever got by without my inexpensive reloading dial calipers! I can't prove it of course, but I feel pretty sure that ALL of the 6" "store brand" dial calipers - Cabela's, Midway, RCBS, Lyman, Hornady, etc. - are made on the same Chinese production line as the much less expensive Harbor Freight versions. HF often has them on "sale" for as little as $14 or so.
I have an old 6" "made in Germany" Craftsman vernier caliper of excellant quality plus two 6" and a 12" dial calipers, one from Midway and two from HF. They all read the same on my precision gage blocks, within a half thousant anyway, so the cheaper calipers are plenty good enough for my reloading needs. There is no doubt they aren't Mitutoyo or Starret quality so they won't last as long, but my cheaper tools will likely last longer than I will so who cares?
If you need to use your calipers daily in a machine shop, get the better ones. But for reloading, get one of the cheepies and spend the (large amount) of saved money on components!
