One of which - the HD33 - gets you into 3D for just $1,499.
The folks at Optoma have a lot of projectors to show off, but perhaps the most interesting to those with a limited home theater budget is the HD33, which displays 3D content at 1080p for a price of $1,499. It supports anything HDMI 1.4 and can be set to enable non-HDMI 1.4 3D signals from game systems and set-top boxes.
The HD3300 steps things up a bit by adding features like PureMotion3D and PureD to enhance your 3D experience. It also boasts a new color processing system and ISFccc controls so you can get everything just right. You can pick it up now for $1,999.
At the top of the line is the HD8300, which includes PureMotion4D - the projector can't actually travel through time, but that doesn't mean you can't pretend it's a TARDIS. You'll also find Pure Shift lens shift, ISFccc controls and separate day and night modes. The HD8300 comes in at $4,499.
