I remember reading that Sony stopped making 19" CRT's, or was it 17"? Anyways, I recommend a Sony, or a NEC/Mitsubishi, or a Viewsonic. You could probably get the Viewsonic 19" A90f+ for ~$200 (Bestbuy has it for $230, saw it couple of days back in store). Flat screen, .25dp, good image quality, plus the thing I liked was they have this button that makes it really bright "Ultrabrite". The feature could be really helpful in games, in dark areas, I remember having to turn the brightness up and down on my monitor whenever I wanted to play.
I personally am on a KDS AV195TF (Sony FD Trinitron tube), great picture quality from the tube. But I have mixed feelings about KDS. I bought their monitor 4 years ago, when it had a Trinitron tube, not the FD one. Paid a ton for it, but I had wanted a 19" and a trinitron. Well, took 4 monitors before I got this one that I am currently using (this is my 5th one, has lasted the longest and hope it keeps working 🙂 fingers crossed). Their warranty policy has to be given credit here. Their "Kares" program paid for the shipping of each one of those monitors (except one, long story), and then would ship me one first, and when I had tried it, I would call them up and they would arrange the pickup at my convenience. At times I would call em 2 months later and they would not charge the credit card they had on file. Did this for 3 years from the date I bought the original monitor. I believe viewsonic requires you to pay shipping if something goes wrong with the monitor. Best warranty plan I know off, but iffy product.
Anyways, done ranting 🙂 hope that helped someone.
