Two Pens, No Waiting
The latest interactive projectors from Epson take its BrightLink technology to a new level with the ability to use two pens at once. Think of the possibilities of a race among kids to finish a math problem or a teacher and student working together and you get an idea of its potential. The BrightLink 425Wi, 430i and 435Wi sell for between $1,300 and $1,400, connect with a computer via HDMI and put out between 2,500- and 3,000-lumens. A big bonus is that the replacement lamps for these projectors cost $99, half what others go for.
