CPO Outlets via Rakuten offers the factory-refurbished Black & Decker 18-volt 12" Cordless Electric Trimmer, model no. NST2118, for $39.99 with free shipping. That's $48 under the lowest total price we could find for a new unit, although we saw a refurb for $5 less last fall. It features two 18-volt NiCad batteries, telescoping shaft, automatic line advance, and gear drive transmission.
