Amazon offers the Sun Joe Mow Joe 14" 12-amp Corded Electric Mower for $79 with free shipping. That's $11 under our mention from July and the lowest price we've seen. (It's also the best deal we could find now by $20, outside of the mentions below.) It features a steel blade with 14" wide cutting path, detachable grass catcher, and adjustable 3-position cutting height.
Close prices: Walmart and Hayneedle have it for a buck more.
