DIY LCD Projector

I have been a bit obsessed lately about building my own LCD Projector.  For those that don't know, you can build one pretty simply.  Good plans can be found at LumenLab.

I have settled on a box design, and am now looking for the ideal LCD to strip.  The preference would be for a 15" HDTV with just about every input type available.  I am looking at this samsung 15", though I think it requires an add-on component to do HDTV properly.

Anyone know of any other LCD that as the inputs I need (component is ideal, DVI, HDMI, and a build in tv tuner)?

Related to this is that I want to hook this up to my Media Center.  Now, the PC's I have now are 2004 Media Center PC's so HDTV isn't an option at all.  And upgrading seems scetchy at best.  So, time for another dedicated media machine. 

The projector is going to be ceiling mount.  I have already wired my walls in the new house for coaxial and cat 5.   A media center extender can connect to my PC through cat 5, and then through composit to my projector.  The hitch, the media center extender doesn't seem to support HDTV.  This page seems to say say no.

Media Center 2005 PC - Useful Concept
the extender that does NOT support HDTV - not so useful.
