Get an 8 bit, rather than a 6 bit.
I would avoid both the Hanns and the Chime. Both have early failure rates and sometimes fuzzy screens. I would also avoid the Viewsonics.
Out of the New Egg choices, I would choose these Samsungs over the Hanns or Chime: 216BW, 920nW (my choice), 245BW, 204 BW 226BW, 225BW, and 906BW. Followed by the Acer.
Other good ones not at New Egg: Sharp, Sony, some HP, NEC, Phillips.
Read the specifications very carefully. One detail most miss, is the ability to see from the side angles, and the ability to adjust the monitor up and down... the low priced ones sometimes have good screens but allow no adjustments.
Also, it is very important to get a three, four, or five year warranty... and the freedom to return any with bad pixels.
Don't get any that have speakers built into the LCD frame.
