Walmart offers the refurbished Brother WiFi Monochrome Laser Printer for $54.99 with free shipping. That's $2 under our mention from three weeks ago and the lowest price we could find by $9. It features up to 2400x600 dpi printing, up to 24 ppm print speeds, a 250-sheet paper tray, a 250-sheet automatic feeder, 802.11n wireless, and USB.

Note: A 1-year warranty applies, but it's unclear who backs it.
