bentwookie: i encourage you to find a place that has both. A local school, library, etc. I have a Dell 17" LCD and a Sony G420P CRT (19" Trinitron). For pure graphics work, there is no comparison--the CRT's colors are better, the image is sharper. And it runs at 1600x1200 (which is nice for photochop).
BUT, I must say, the LCD is GREAT for text and/or browsing--less eye-strain and clean, crisp text. Ideally, owning both is great--I found that out recently.

But if I had to go with one, it would be a CRT.
Oh, and the Dell you're talking about--the 1800FP--is a good LCD (and they're selling at a good price right now.
