Dirty Projectors was created in 2002.

Infocus projectors are made for the office, home, classroom, and for all presentation needs. Infocus projectors can also be useful in churches and the courtroom. The projectors are for presentation purposes.

LCD projectors are by far the best

Most projectors have the means to be a rear and front projection system. The only projectors that are unable to do this are the cheaper projectors you find at Office Depot used for powerpoint shows.

NEC's multimedia projectors cost from $310 to about $5,000. They also make cinema projectors which are even more expensive.
