Worx GT via eBay offers the factory-refurbished Worx 20-volt Lithium Cordless Grass Trimmer, model no. WG155, for $42.99 with free shipping. That's $7 under our August mention of a refurb and the lowest total price we've seen. (It's also $48 under the lowest total price we could find for a new unit.) It features an adjustable shaft, tilting head, flower guard, and more. A 2-year Worx warranty applies.

Note that these units have been slightly tested and may have light scuff marks on them. They are also shipped in a plain brown shipping box.
