Walmart offers the refurbished Brother 17-Stitch Sewing Machine, model no. JX2517, for $29.97. Opt for in-store pickup to avoid the $5.97 shipping fee. That's $20 below our mention of a new one from five days ago and $63 under the best we could find for a new one today. It features 17 built-in stitches, an automatic 4-step buttonhole maker, jam-resistant quick-set drop-in top bobbin, and LED-lit work area.
A 25-year warranty applies, although it is unclear who backs it.
