Cheap? Buy Acer AL1916B 19".
It's black, it's 12ms, and it's not that bad for a price that I see of $330 canadian dollars at wholesalers.
Try to find that model in your local area.
Also, make sure to read Acer's Pixel Policy
"Acer has a formula and breaks up the screen into sections and defines which area's carry more weight in terms of importance -- if there's more than one dead pixel in the center Acer will replace a laptop, but if the pixels are elsewhere then you can suffer from up to 4 dead pixels per million on the screen."
