I had a top-of-the-line projection HDTV from Toshiba.
All I can say is that unless you watch DVD's only, your digital cable feed (as mine is) is going to give you a crappy picture. Cable feed is crappy to begin with, but it's
accentuated on a good projection set.
Since I watch more cable than anything else, I returned the projection TV, for a Sony WEGA 36". Now the cable picture is translated acceptably and not with
moving/crawling pixels from the HDTV Projection set (even a digital convergence did NOT solve this problem or returning it for another same model number).
My recommendation: tube tvs will always BEAT ANY projection TV--even HDTV projection sets. You can only argue this point if you have a DVD player. Even Mitsubishi's acclaimed Diamond Series can't translate cable well. 'Nuff said.
