Anyone know of a battery operated or some sort of prophy handpiece that could be used at home? - disposable prophy angles

I am currently a student at DH and get tons of free samples! Well, I was at a conference today and tons of disposable prophylaxis angles and prophylaxis paste. I know it sounds crazy, but probably no such thing as a hand piece that, for use at home to be purchased with the family members of the practice? We have learned the technique and I'm dying at home with my practice, gifts! I ask this because someone told me it was not something you can buy at Rite Aid? Any input?
