I've had a 19' Viewsonic A90 for many years.  Still has a perfect picture.
When I got a new game machine a year+ ago, I bought a $90 17'MAC POS for the old machine, and put the A90 on my game machine.  
Well, the MAC never had a clear picture, and lately its started hissing, getting burryer, losing color, and getting worse by the day.
So I went to Best Buy and bought a 19' Viewsonic A90f+ Flatscreen for $230.  Its on the game machine now, and the old A90 is on the old machine.  
Great monitor, affordable, and flat, no glare.  
Get one.
