While LCD's have been getting better and better, and cheaper and cheaper you might be able to get a CRT that looks better for the same or less money. The killer with a CRT will be shipping, if you didn't buy it locally. A little less than 2 years ago I went from dual 19" CRT's to one 19" LCD, primarialy to save space. While the LCD is a tad brighter, it still doesn't equal the color accuracy of the old CRT.
Having said that, if you do buy an LCD, get one with the DVI connection. It is very important at higher resolutions, for better image quality. Just make sure that your computer has one of these as well, you can get an adapter, but that kind of defeats the purpose.
It doesn't look like they have any great deals right now, but Dell often has some good deals on their LCD's which are some of the best out there. If you keep your eye on slickdeals.net or any of the "bargain hunting" web sites these deals pop up pretty often.
