Casio XJS32

"The Casio XJ-S32 is the slimest projector ever, thin enough to easily fit in a briefcase with room to spare. Don't be fooled by the small size though, whilst the unit is incredibly portable and easy to use, it is extemely powerful. The XJ-S32 has some serious power, it features a surprising 2300 lumens brightness allowing for presentations in lit rooms. The unit also has a 1800:1 contrast ratio providing good deep colour and rich blacks. Casio has also included a handy 2X optical zoom function, giving you more flexibility, great for presentations in smaller rooms or where there isn't much space for placement of the projector."
