Staples offers the Canon imageCLASS WiFi Monochrome Laser Printer, model no. LBP6030w, for $49.99 with free shipping. (
Amazon offers it for the same price.) That's tied with our mention from two weeks ago as the lowest total price we've seen. (It's a current price low by $7, although most stores charge $100.) It features a print speed of up to 19 ppm, 32MB print memory, 802.11n, USB, and a 150-page paper capacity.
