For the functionality you need at an affordable price, choose the lightweight (2.9 kg) SD206U. This projector combines SVGA resolution with DLP™ Technology from Texas Instruments, supporting a contrast ratio of 2000:1 and delivering 2000 lumens of brightness for crisp images and rich colors, even in classrooms with ambient light.

It comes with an instant shut-down feature, handy when moving from classroom to classroom. But it's also RS232C compliant, so it can be used as a permanent projector.

Other features include digital keystone correction, a 10-level white enhancement function, a full-function remote control, a variety of input/output ports for connectivity, and a long-life lamp rated up to 3000 hours (low mode). It also comes with an anti-theft security hook.
