Another Vote goes to 900nf.
I recommended this monitor to my friend and he bought it.
I saw it and I liked it very much. He has viewsonic pf790 at work, 19 in, and he says it can't compare to 900nf, but still is good.
I, myself placed an order for 21 in. one, 1200nf, few days ago, still waiting.
Thank LXi and others for recommending this model to me.
