3M Streaming Projector for $170. It is a very tiny projector meant for beaming a video on a wall. At only 60 lumens and 480p resolution, the picture quality will be low and not that bright, but some reviews say this projector was very useful. It has an HDMI input, so anything that works with HDMI, like if you have an HDMI interface for your iPad, iPhone, tablet, or PC, it will project the display on a wall.

If you are looking for a home theater projector, a 720p projector usually sells for around $550 and a 1080p for around $800 to $1300.
