Black & Decker via eBay offers its factory-refurbished Black & Decker 3.6-volt SmartDriver Lithium Screwdriver, model no. LI4000R, for $19.99 with free shipping. That's tied with last month's mention and the lowest total price we could find for a refurb by $2. Features include a magnetic tip for holding screws, SmartSelect clutch to prevent stripping, forward/reverse window, built-in LED light, and table-top charger. A 2-year Black & Decker warranty applies.
