I often go to the local Craigslist looking for deals on machinist tools. That usually means metrology tools such as micrometers, calipers and the like.
Today I got two sets of gauge pins, the "inch" size in the "minus" tolerance range. This means nominal to -0.0002" size. The sets are 0.060" to 0.250" and 0.251" to 0.500". Between the two sets of these Chinese made ones there's about 14 pins missing, so I talked the guy down to $40 from his asking price of $70. A good many of the pins in the 0.251"-0.500" set still have the original anti-rust protective wrap on them.
He also had screw thread plug gauges, so I got #8-32UNC 2B, #10-32UNF 2B, 1/4-20UNC 2B and 3/8-16UNC2B go/no-go gauges, plus 1/8-27 NPT and 1/4-14 NPT gauges. $60 for those wasn't as good of a deal but the pipe thread gauges alone are worth it because they're rather hard to find on the used market and always in good condition (as these are.)

Not a bad haul for $100. Having quit the cigars, I can restart with some long overdue tool acquisitions.
