Ok, here's my story if you want to hear it. I recently made the switch, so you might be interested. I used to use a nice 17" dell CRT monitor. I hated the idea of LCD monitors. Back lite, so no true black, ghosting if the pixels turn on and off to slow, can't show colors correctly unless you get the best monitors so they use "dithering", etc.
My wife's 21" monitor was died, so I have to get a replacement. We went out and bought her a 19", 5ms, LCD. Before I hooked it up to her system, I tested it on mine to see if I could see the color problem, ghosting, etc. I fired up TF2, and gamed for a bit. The colors were way off, but I didn't see the ghosting 95% of the time. (only when I turned REALLY fast, which almost never happens in that game.) The colors was the biggest problem I had, they looked badly faded. I realized however I could adjust that, so I set off to get my own.
I found one online and bought it. 20", 5ms HP LCD. For whatever reason, the colors weren't faded when I hooked it up to mine, though the limited ghosting problem remained. I was afraid I'd need a new video card, I wasn't sure my 8800GS would handle the new 1680x1050 res. I was happy to see I could keep the details maxed, and still use 2x MSAA in TF2. I have a larger display, and only ghosts if I try. The colors look great, and I'm pretty happy.
I got lucky buying online. If you want one, and have the $$$ and serious about gaming, go to a store and look at their 2ms models. Buy one that looks good to you. Unless your eyesight is a lot better then mine, you'll be pretty happy.
