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

Despite its average picture quality in our tests, the X1160 is a suitable projector for the business person who frequently goes on the road to give presentations, or for the user who wants an inexpensive big-screen for a home theatre setup.

This isn't a brilliant projector by any means, but with a little patience, it will perform well enough for most users at a competitive price.

A cheap purchase if you don't mind the noise.

BenQ's PB-6110 projector offers high brightness and contrast levels, and while it offers good all-round performance, the 4:3 aspect ratio makes it better for presentations than watching movies.

The InFocus Work Big IN26 is a good all-round projector that can handle a wide range of sources and has above average image quality. If you are in the market for an attractive unit with good performance, you should give this model a look.

Sony's VPLES2 produces bright images, though the lens slightly distorts the image at the corners.

The EMP-S3 provides a huge, bright image for a relatively low price.

Great colour reproduction and an inexpensive, portable package allow the ViewSonic PJ402D to serve as both a presentation and home theatre projector, albeit in a 4:3 aspect ratio.

The EX20 from Toshiba is great for small rooms. It also has wireless connectivity — an unusual but useful feature in a projector.

The TDP-S25 improves on its S20 predecessor, but still lags behind competitors.
