You can buy these with a calibration certificate for like $70, but I skipped the cert. Should be the same quality, cost me $16. I chose the version with the superior units of measurement.
Got one of these a while back but it broke. Though even before that I still preferred my cheap, auto-locking Stanley tapes. And I have several Starrett combo squares and calipers, so I'm aware of the brand reputation, but I believe these are manufactured overseas and they just slap the Starrett name on them.
