I have a NEC E750 right now and it was pretty good back in the day when I bought it.
It's not flat but its not a fishing bowl. Mine does 1600x1200 at 70 Hz but I would not recommend running it at that res because the text is just too small. Besides at 65 Hz most people see the flicker. I see some flicker even at 85 Hz (depending on the lighting). Colors are pretty much balanced and text is really crisp.
If you want to run 1600 by 1200, buy a decent 19 inch because everything is simply too small + flicker on a 17 inch.
Beware of refurbs though...
EDIT: Oh btw, every monitor is unique and so even if you buy two of the same model, they may have slightly varying characteristics.
