I tested a pair of Harbor Freight calipers on a set of gage blocks at work, and they were accurate. They don't always drive exactly to zero, as one other post mentioned. Something I did notice is that the newer Mitutoyo calipers at work have a much faster display update, making them considerably easier to use. They also had more smooth motion, though this is subjective. For home use, bike repair, etc., the cheapies are good enough. Given that my colleagues prefer digital, I've got the cast-away dial calipers and am perfectly happy with them, plus an old Mitutoyo vernier at home that I use, just because.
