The design of data projectors hasn't changed in recent times and the InFocus IN10 (£800 inc. VAT) sports a similar design to the machine it's replacing. However, what has changed are its internal controllers and the overall picture quality

Small and lightweight, Easy to set up, Good data projector

Noisy fan, Not brilliant with multimedia

A handy and portable offering for first-timers

The BenQ MP611 stands out in a number of respects. For one thing, it is dark blue in colour, which is certainly unusual, and the nine metal control buttons look stylish and smart

Attractive price, Pleasantly quiet

Limited resolution, Little point in tweaking settings

It's pitched at a low price, but too many compromises have been made to get there

The InFocus IN26 plus is an amended version of the IN26 which has the brightness rating boosted from 1700 to 2200 ANSI lumens.The styling is very boxy, with a flat top that has the 12 control buttons set into the surface

Reasonable price, Decent brightness

Unacceptably noisy, Crude adjustments

A reasonable performer but for us the noise of the cooling fan is a deal-breaker

If the Optoma DX733 was judged on looks and styling alone it would be a hands-down winner. The casing is two-tone silver with a curved bulge to accommodate the lens housing, while the control buttons are neatly and logically laid out

Brings multimedia and movies to life, Improved colour production, Good looking, Clear and detailed image

Poor battery life, No DVD rewriter, Quite difficult to adjust focus

A powerful and accomplished projector that looks good too

The Acer is a chunky projector that is based around a bright DLP chip that works well even in a sunny room. It's got a row of connections that give a choice of DVI, VGA, S-Video and composite, plus an audio connection, USB for the mouse and a VGA output

Performs well in bright rooms

Slightly noisy, Colours could be better

A competent, if not exceptional, DLP projector that won't leave you disappointed

Optoma is an increasingly popular brand, both with business and schools, as it offers a wide range of affordable DLP machines. The Optoma EP770 is a replacement for the older EP739 and is aimed at meeting rooms and classrooms

Excellent value for money, Five-colour wheel, 3000 ANSI lumens

Could be more portable, Slightly dull looks

It may lack some of the flair of rival models, but in terms of features for the price, the EP770 is hard to argue with
