Amazon offers the Philips Sonicare 2 Series Plaque Control Sonic Electric Toothbrush in five colors (Black pictured) for $39.95. Clip the $10 off coupon on the product page to cut the price to $29.95. With free shipping, that's tied with our December mention and the lowest price we could find by $10. It features sonic cleaning, up to 31,000 brush strokes per minute, a 2-minute timer, and Sonicare charger.

Update: Even better, Newegg has it in Black or Sky Blue for $39.95 before coupon code "EMCRFRJ32", $27.95 after. With free shipping, that's $2 under the above mention and the best we've seen.
