I have a Viewsonic A75f and it is an awesome monitor. I chose it over a KDS model that was similar in specs/price, after staring at them for some time at Office Depot.
Monitors are subjective, so the best thing to do is go to Office Depot, Office Max, Staples, Circuit City and/or Best Buy and just look at the various models and decide which one you like, then see if you can get a better deal online. (The model numbers may change when you look at them online, a quick specs check should solve that problem)
I really like the Flat Screen of my Viewsonic, and the coating which cuts down on most of the reflection from other light sources around the room. I decided a excellent 17" would better suit me than a lesser 19", and haven't regreted it since. The price of the A75f has fallen dramatically, so you might start there and see if you like it. My 0.02 Hope this helps
