Im using a viewsonic A91f+ its pretty good as far as I can tell I dont like LCD's so my choices at Best Buy where pretty limited when my old monitor blew up lol anyway I think it was around 250ish when I bought it so its probably cheaper now ?
I couldnt find it on newegg but they did have these ones
The thing I like about it (im not sure if other brands have this or not) there is this button you push and you can have 3 different custom settings for brightness and all that. I set mine up one for watching video's and one for at night and one for in the day time.
Since your looking for a CRT for a designer I would look for one with a pretty high resolution and the lowest dot pitch you can find. The lower the number usually the sharper the picture and the better the picture quality. But not always, there are several mitigating factors. Either way start by looking for the lowest dot pitch you can find in your price range and if you have the oppurtunity take a look at the image quality yourself.
