I personally have a Hercules Prophetview 920pro myself. I have no problems whatsoever with the monitor in games, movies, and simple webpage/wordprocessing tasks. They are however, next to impossible to find at this current time.
The next monitor I would recommend due to the feedback I've heard is the Viewsonic VP171B. Most people I've heard of that have this monitor love it. I'd rate the display characteristics as second best, but first in features available for the price.
