I would give a big thumbs up to Diamond Pros as well. I own two (an older 19" 900u and a newer 21"2040u) and they are the best CRTs I have used (I have a Sony 21" G520p as well and a 15" Sony of some sort) and the Mitsubishi's are better in my opinion. And most other people I know that have owned or used both Diamond Pros and Sony's.
I just recently switched to LCDs though and prefer it to all my CRTs
I don't plan on ever buying another CRT but if I had to I would get another Diamond Pro.
