    My dentist recommended an electric toothbrush, I saw at Target I could get one that takes AA batteries for about half the price of a rechargeable one. I have a large stock of NiMH rechargeable AA batteries so when it runs out I can pick out batteries from the bin. I change batteries once a month or so, the laser charger doesn't seem too necessary to me.
