FatWallet has Dell coupons almost weekly that can bring a Dell 2005FPW 20" to $450 and a 2405FPW to $850.
I like my 2005FPW but yeah the black point sucks. Colors look really good on it to my eyes, and the brightness is almost too much to be honest. You can not look at it in a darkish room without hurting your eyes! It made my 19" CRT look washed out, dark, and blurry. I was considering dual head until I put them side by side finally. And that was one of the best 19" CRTs I've seen over the last 5-6 years.
Rotating these widescreen behemoths to portrait mode makes for fantastic web browsing! I can set that up in about 2 seconds with ATI's drivers too. Just right click on the taskbar icon and go to rotation I believe. Then grab the screen and rotate it. The Dells rotate clockwise on their mounts.
Only disappointment for me was the inability to do picture-in-picture with DVI and VGA. I love the 4 extra USB ports right on the monitor, and I do use both VGA and DVI together for separate PCs.
Just don't play Doom3 on a LCD if you don't have to. The black point problem ruins the game a bit.
