Microsoft Store offers the MakerBot Replicator Mini Compact 3D Printer, model no. MP05925, for $1,275 with free shipping. (Newegg via eBay has it for a buck more.) That's the lowest total price we could find by $100, although we saw it for $100 less a month ago. It features a 200 micron layer resolution, 75-cubic inch build volume, USB, WiFi, and 320x240 onboard camera.
