Mitsu 73": Best ("Biggest") Bang for Buck?

[6volt]

73" for under $3000 about says it all in my book for a non-front projector. I don't like the idea of a projection bulb but what other alternative is there?

I value size over all other attributes (used to have a GE front proj SD running at 11.5' on white drywall with 11.5' viewing distance which I loved. Yeah it was dark, yeah you could count the lines, but it was BIG)

Actually, I'm exaggerating a bit. While there is nothing that can compare with a display the size of one wall of a room. There is something to be said about a non-front that is bright and doesn't turn room into a cave.
