The Viewsonic PJD6211 is the most cost-effective data projector here. It takes the standard design route for a DLP device, being a squat device that sits length-wise with the lens fixed at one end and a large vent along the front. It's quite compact but with a weight of 2.6kg, is not ideal for taking on the road. You will find it is a decent machine for sharing between rooms in an office, or possibly a school.
