any way i have a samsung 730B 17inch 12ms, cant remeber the contrast ratio, but im more then happy with it. it was about $300 when i purchased it, it also seems kind of small now, dont get anything smaller then a 19inch. my friend has a 19inch viewsonic, and absolutely loves it. my best advice would go to best buy and look at them and see which one you like most, check the reviews see which is the best for 350. make sure you get a decent dvi cable, i ended up getting a cable that was to long, a 6ft cable should be long enough.
also i had one bum pixel too.
btw samsung has pretty good software for adjusting their monitors through windows.
The various Dell 19" LCD monitors can be found for some pretty darn low prices at times, as I got a Dell E196FP for about $265 many months ago, and, despite it's VGA only input, it's quite nice/big/bright for the money, and I certainly cannot detect any ghosting during gaming, for which this monitor is used about 3 hours per day!
