Regulator. LM 7805. Best option.

a linear regulator is the cheapest option - not the most efficient - there are digital switching supplies that bump the voltage up or down (boost or buck) at near 95% efficiency, where the lm7805 burns off more than half the energy to drop the voltage down to the required level. Just a thought.
