A great combination of portability and functionality, the Panasonic PT-LB51E is an attractive option for businesses looking for a lightweight and easy to use projector.

Acer's P1265 is large and heavy when compared to other portable models, but has impressive brightness and image quality.

The DX130 produces a bright image with strong colours for a portable projector. However, it is hampered slightly by the DLP 'rainbow effect' and its noisy fan.

The Viewsonic PJ551 is a model that targets the budget-conscious consumer, and it performs solidly. It may not have class-leading specifications, but for the price it's definitely a good choice.

There are smaller and lighter portable projectors available. If you want a model that's able to reproduce colours well and give great presentations, the PGF312X will fit the bill.

For a model that's marginally portable the Sanyo PLC-XU105 produces an incredibly bright picture. It doesn't display the richest and most colourful pictures, however.
