Geekdeal via eBay offers the factory-refurbished MakerBot Replicator Fifth-Generation 3D Printer for $749.99 with free shipping. That's $55 below our mention from last month and the lowest price we've seen for this printer in any condition. (It's the best deal now for a refurb by $450 and $1,810 less than buying new.) It allows you to create professional-quality models with a 100-micron layer-height resolution capability and a 456-cubic inch build volume. Features include a 3.5" full-color LCD, smart extruder, on-board 640x480 camera, WiFi, Ethernet, and USB. A 1-year MakerBot warranty applies.
