Walmart offers the Sun Joe 16" 12-Amp Electric Garden Tiller/Cultivator for $88.52 with free shipping. (Amazon has it for the same.) That's $10 under our September mention and the lowest price we've seen. (It's the best price now by $11.) It features a foldable handle and three-position wheel adjustment and cultivates up to 16" x 8".

Update: It's now out of stock at Walmart; however, Amazon still offers it for the same price.
