People in the projector industry like to keep some things secret, but if you ever visit Taiwan, some interesting secrets may reveal themselves. For instance, I recently discovered that Acer in Taiwan makes the projector that Proxima calls the DS2, as well as an almost identical unit for 3M called the MP7630. The models have differences, to be sure, but the secret of their parentage is out. Acer seems to have had a hard time meeting its weight spec, however, since neither unit weighed the advertised 5 pounds, with or without the video module, which added about 0.6 to 0.7 pounds to the bare projector on my scale. To save weight, though, you can always remove the video module when you don't need it.
