Recommend you install Gamespy Arcade or one of the other shareware games browsers out there.
Gamespy is a bloater and advertising hell... but you can use it compile lists of "good" servers by simply copying addresses out and into a document of your own, or by marking servers as favourites in your games of choice.
Or you could try All Seeing Eye, seems a lot faster to use the gamespy.
