Black & Decker via eBay offers the factory-refurbished Black & Decker 22" 18-volt NiCAD Hedge Trimmer, model no. NHT2218, for $29.99 with free shipping. That's $4 under our December mention of a refurb and the lowest total price we've seen. (It's also $30 under the lowest total price we could find for a new unit.) It features 22" dual-action blades, an 18-volt NiCad rechargeable battery, and purportedly cuts branches up to 0.75" thick and trims up to 1,200 square feet per charge. A 2-year Black & Decker warranty applies.
