Even the old commodore 1084's were quite good. Razor sharp image and all. That being said, between shipping costs and the fact that they are 20-30 year old CRT monitors, you might end up spending a lot of money for a monitor that can die at any moment.
These days, I'd get one of the LCD's that support the NTSC input and be done with it. Picture quality isn't quite as sharp, but it'll be cheaper in the long run.
