The Viewsonic VG191 is as good as it gets for the money - as far as I have read. I've been shopping one too - think I found one for about $1200 somewhere. But I keep hearing some people say a good CRT is still better. I haven't been able to see enough screens to be able to judge.
I have a Viewsonic G790 19" and would love the extra space - but for that kind of $$ I'd feel pretty stupid if it wasn't a big visual improvement too.
