I'm with Harbour Freight on this one. I do have an expensive set (Mitutoyo) which I use around QC people at some of my customers, for the more industrial customers and farms I use a set of Harbour Freights. Their accurate enough for general use and if I drop them climbing over equipment in the process I'm not crying over my Mitutoyo. I once dropped an expensive dial caliper and it was never the same afterwards. It also helps as there a Harbour Freight in town.
