Newegg offers the refurbished 3-lb. Dell Latitude E7240 Intel Haswell Core i7 2.1GHz 12.5" Laptop bundled with a XYZprinting Da Vinci 3D Pen for $539.99. Redeem this $30 mail-in rebate to cut the price to $509.99. With free shipping, that's $45 under the lowest total price we could find for the pen and a similar refurbished laptop elsewhere. It features an Intel Haswell Core i7-4600U 2.1GHz dual-core processor, 12.5" 1920x1080 LED-backlit LCD, 4GB RAM, 256GB SSD, 802.11ac wireless, Bluetooth 4.0, USB 3.0, 4-cell battery, and Windows 8.1 Pro 64-bit. Rebate expires October 31.

A 3-year warranty applies, but it's unclear who backs it.
