CPO via eBay offers the refurbished Black & Decker 13-amp Corded Mower, model no. MM2000, for $114.99 with free shipping. That's $80 under the lowest total price we could find for a new one. It features a 20" cutting width, 13-gallon collection bag, and 7-setting height adjustment.

A 2-year warranty applies, but it's not clear who backs it.
