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.

Believe it or not, but this is how CPUs and other microchips are handled. For a specific architecture, the chip is tested and depending on how many cores are working and how well it performs, it will be sold as say i3, i5 or i7 (in case of Intel).
