Epson offers its factory-refurbished Epson VS210 SVGA LCD Multimedia Projector, model no. V11H433020, for $279 with free shipping. That's tied with our September mention as the lowest total price we've seen. (It's also $119 under the lowest total price we could find for a new one.) It features an 800x600 native resolution, keystone correction, 3,000:1 contrast, USB, and VGA and other video inputs. A 90-day Epson lamp warranty applies, while the projector itself is covered for one year.
A close price, Gov Group has a refurb for $259.70 plus $19.78 for shipping.
