Product: Epson Powerlite Presenter

The Epson PowerLite Presenter portable projector and DVD player combo includes two 10-watt speakers with virtual surround sound, microphone support, and built-in closed-captioning capabilities. WXGA resolution displays content from wide-screen notebooks, and the unit supports a host of input devices, such as a camcorder, a digital camera, and an iPod.PROS: The USB plug-and-play connectivity makes for easy setup and eliminates toggling between projector and display. The controls are easy to use and well defined. The PowerLite Presenter projects in native 16:10 (WXGA) aspect ratio as well as 4:3 and 16:9 aspect ratios and offers USB connectivity for viewing JPG images without a computer. The built-in microphone is a nice feature.CONS: Cannot be mounted on a stationary mount. The 10-watt speakers may not be powerful enough for all locations.OVERALL EVALUATION: The variety of inputs and the clarity of the controls make this projector an excellent choice for anyone looking for a mobile projector in the mid-price range. The HD projection at an aspect ratio of 16:10 makes wide-screen viewing a real pleasure. Every school needs a couple of mobile projectors, and this one is designed for mobility.www.epsonbrighterfutures.comPrice: $808 through the Brighter Futures program

LUMENS PS660 VISUAL PRESENTER

The Lumens PS660 SXGA desktop visual presenter offers one-touch integrated audio and video recording and has an HDMI interface for transmitting uncompressed digital data. The presenter has a large capture area and includes HD resolution and the ability to store 240 images internally. Since the PS660 integrates with most interactive whiteboards, labeling images and saving lessons are no problem. Because it records to a standard SD memory card, teachers can save prerecorded lessons to play back at a later date. PROS: The presenter is fully integrated with interactive whiteboards and built-in audio and video recording. It records to a standard SD memory card and has a 15X optical zoom with auto focus at end of the zoom. The HDMI output, at 1,080p, allows direct connection to high-definition media sources with one cable. The software has TWAIN/WIA support for both PC and Mac. The large capture area has more than enough lighting. The controls are well labeled and easy to use. Recording (audio and video) is done with the touch of one button (the presenter does not have to record from an attached computer, as do many of its competitors).CONS: None.OVERALL IMPRESSION: The PS660 is a little pricier than some other visual presenters on the market, but its features make it worth the cost. An experienced user would make good use of the extended features, such as the HD output and recording to the SD memory card. Perhaps the PS660’s most impressive feature is its ability to perform both audio and video with one touch.www.mylumens.comPrice: List, $1,995; education, $1,499
