My old manual calipers went missing a few months ago. I finally gave up looking and bought some new digital calipers today. I thought this deal was good enough to share. $12.39 (free shipping with Amazon Prime), and includes an extra battery and case. Regular price is $49.99, though I'd take that MSRP with a grain of salt. Accurate to within .01mm. I haven't tried them yet, but the reviews are solid.
