Just a quick note for anyone who may be considering one of the ~$50 gauge pin sets from Amazon or Ebay, the set I ordered came in a couple of days ago and I have to say I’m impressed with the value. Granted I can’t vouch for the +0.0000 / -0.0002 tolerancing for even one of the pins, much less all 190pcs. My interest is just having a finely graduated set of gauge pins…and for that it looks perfect.
