Newegg via eBay offers the Acer 1080p 3D DLP Projector, model no. H6510BD, for $499.99 with free shipping. That's tied with last month's mention and the lowest total price we've seen. (It's a current low by $67.) It features a 1920x1080 (1080p) native resolution, 3,000 lumens brightness, 2D to 3D conversion, and two HDMI inputs.
