When I found out that Optoma was taking over the entry level projector market – excuse me, I mean introducing a 720p DLP projector for under $1000 – I quickly lined up a unit for review. You heard correctly, this is a 720p-native DLP projector that is debuting for $999 (street price). To suggest that this projector might be a popular item going into the holiday season and throughout 2007 would be like saying that Reality television might be getting a bit stale. I’ll just say it now – this should be the top-selling projector of the coming year, and for good reasons that I will outline in this review.
