Due to their price and how long they have been around, I would imagine
that the CRT rear-projection would be the most popular. I bought my
1080i rear-projection about 2 1/2 years ago. At least around here
rear-projection 1080i is more popular although DLP and LCD rear
projections (and to a lesser extent plasmas) are starting to come on
Hmm, in this email you change the phrase "like most" which you have used
in a few emails to "sold today". Ok, we understand now. Thanks ;-)
