I voted CRT because you get more resolution for your buck, and they last forever. I had my 7 year old 15" as my 2nd monitor until a couple days ago. It flickered and popped to death while I was 6 tabling. But how long do you think that LCD will last.
But then, if you are crushing the tables 8 at a time, I guess that extra few bucks is worth it.
If you do get an LCD, the Dell 2001 FP is definately the way to go. You can get them off Ebay, new for <$400.
