Well i've finally had enough of this crap of LCD's not having a less resonse time than 25ms on a 19". I dont really play that many games anyway. I finally found a 700:1 19" monitor that i really liked (i'm fussy about specs and the look of the LCD). Its the new Planar
I'm trying to patient as well for a 19 or 20 inch LCD with a response time <20 ms. Looks like it might be a while.
To answer your question, try taking a look at:
1) NEC 1980SX (700:1)
Viewsonic also has several models that are 600:1. They are:
I'm also partial to the new Planar PX191. Seems like a great monitor. I think I'm going to push it up one more inch and get the PL201, though. I think I'll like the bigger real estate and the 1600x1200 resolution over the 1280x1024.
