Datavis via Buy.com still offers the refurbished 3M MPro120 LCOS Pocket Projector, model no. 78-9236-7713-8, for $99 with free shipping. That's tied with our mention of a refurb from three weeks ago and $171 under the lowest total price we could find for a new unit today. It projects widescreen images of up to 50" and features a 640x480 native resolution, 200:1 contrast ratio, 12 ANSI lumens, built-in speaker, 20,000-hour LED light source, VGA output, and more.

Note: A 1-year warranty applies, although it's unclear who backs it.
