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 
strong lately.

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 ;-)
