Harbor Freight Tools (website, and physical stores) is currently having a very good sale on calipers. I prefer the analog dial version, because it never needs a new battery. Also, I prefer one which measures in thousandths-of-an-inch, not millimeters. (But some battery-operated Digital ones have a switch so you can do both inches and millimeters.) Get a stainless steel one, because the "composite" (plastic) ones wear out, becoming inaccurate. Also, if you search the website, you'll find a coupon (or code) good for 20% off the price of one item.
