My AG Neovo E-17 is exceptional. When comapred against a Dell CRT the quality was on occasion a lot better. And although TFTs have a set native resolution, a good TFT can use higher resolutions or lower resolutions with little difference in quality.
The native resolution of 17" TFTs is 1280x1024 anyways, which is a plenty good enough quality for most users. It's usually the highest resolution most graphics cards can support as well.
If you have the room, and are professional, perhaps consider a Triniton or Diamondtron CRT. But if you are just a normal user, stick to TFTs. Anyhow, they are only getting better, CRTs will probably not be on sale much in 2006, which just goes to show manufactueres confidence in TFT technology.
Another thing to note is that TFTs only change the picture on your screen when it neeeds to. For example, if you are on your desktop and you adjust your taskbar, the only part of the screen that will change is the area on the taskbar. The rest of the screen is not altered in anyway, unlike the CRT technology where the whole screen is refreshed - the refresh rate, which is in turn what can cause migraines. I wouldn't ignore the headache effect either, consistent headaches can cause medical problems and affects how well you work.

Hope this helps.
