Epson’s W6 projector is a model that is great for projecting images from a widescreen notebook in the office, as well as for occasional home theatre use.

Viewsonic’s PJ506D may not be up to the same specifications as its competitors, but it provides high-brightness projection at a low cost.

Dell’s M209X is light, well-priced and has a high brightness level. If you can look past the fiddly remote, it’s a great portable data projector.

The home theatre projector has fallen on hard times of late, but don't let that stop you from considering this exceptional model. Both user-friendly and feature rich, it delivers an incredible high-def movie experience for the asking price. Ignore the industry doomsayers: Viewsonic's Pro8100 will make willing converts of anyone who sees it up and running.

BenQ’s W500 is an entry-level 720p home theatre projector with great brightness levels and high quality imagery. Colour accuracy isn’t perfect, and a short zoom limits options for placement. But with such a reasonable price, the W500 is a compelling option for the home cinema enthusiast.

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.

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.

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.

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.

For a business projector the Toshiba SP1 fulfils its role admirably. However, if you need a silent model the SP1 isn’t for you.

As BenQ's flagship projector, the W20000 excels for movie watching, with high brightness and great contrast. It's massive and the fan is a little noisy, but it is a good package.

Panasonic's PT-AE2000U is a projector that performs well compared to its competition, but it needs some tweaking to achieve the best image quality.
