I agree with that assessment on the DLP projectors since we have one 
here (a Proxima) and I can testify that the image is stunning and 
doesn't have the refresh problems associated with LCDs. I would add 
that as the yield of DLP chips from TI has improved, the prices have 
dropped rapidly. Now there is no significant difference between a DLP 
and an LCD panel (except the image, of course).
