Amazon offers the Oral-B Professional Deep Sweep Triaction 1000 Electric Toothbrush, model no. D16.513.U, for $35.99. Clip the $7 off coupon on the product page to cut the price to $28.99. With free shipping, that's the lowest total price we could find by $12, although we saw it for $14 less with rebate hassles in November. It includes a handle, charger, and refill brush head.
