56.iNCH.tv If you don't care about 3D, but you want to put together an affordable and portable 720p HD audio video projection system, you could start with a Draper Traveller 56 iNCH diagonal 15:9 aspect ratio portable pull-up front projection screen in either high contrast grey or matte white.

You could pair it with one of the compact WXGA 1280x768 DLP video projectors that's featured in the slideshow.

Of course, you will also need to separately supply or buy and properly connect one or more high definition sources such as a Blu-ray Disc player, video game console, HDTV tuner/DVR, ROKU, etc using HDMI cable(s).

You will also need to leave a bit of room in your budget for an audio system and perhaps a projector stand.
