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.

Toshiba's miniature TDP-P9 offers a portable solution for business presentations, with the experience only slightly hindered by a loud fan.

The Infocus Work Big IN10 is as tiny as business projectors come and can produce a reasonable image after calibration. It would best be suited to medium-sized boardrooms due to the throw distance and heat production.

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.

The PJ358 doesn't have the best performance on the market but it remains a fairly good projector considering its price tag.

If you are in the market for a good all-round portable projector, the Viewsonic PJ258D will certainly fit the bill.

With its superior brightness, excellent image quality, and easy automated features, the NEC LT35 is a first-class projector for business and home use.

The Canon LV-X5's average performance and features don't stack up well against lower-priced competitors that provide better image quality.

$1299 is well priced for a projector, and despite the PD100's drawbacks, it performs exceptionally well as an all purpose business projector.
