p95 - First paragraph - Only standard and alphaware are available during character creation.
p451 - Cyberware and Bioware Grades - Standard, alphaware, and used are available during character creation.
As a side note, assuming the latter rule is correct and you can purchase Used Alphaware at creation, this combination requires the normal amount of essence, but has -2 availability and 90% of the cost. This lets a starting character buy cyber/bioware cheaper than normal while also getting items with a normal availability of 14. The availability isn't an issue as all cyber/bio in the main rulebook jump from availability 12 to 15/16 so nothing is affected, but future products might have items at 13/14. Either way, the free cost reduction is an issue that should be patched.
