Dude, just get a Samsung 1200NF, and call it a day. The debate between Trinitron vs. Diamondtron NF can go on for years. They've each got their strong points and weak points, but unless you're some anal wacko, you're not going to be even slighty disappointed with either one.
I prefer Diamondtron NF tubes because I have noticed the two tiny gray lines that run across every Trinitron tube (it is noticable against any light-->white colored background) and I think the NF tubes look just as good without the annoying little lines.
