There are plenty of good servers out there. I would reccomend using a program like Qtracker or The All Seeing Eye to find you online games. its much easier to find and arrange games then, you can have multiple favorite folders and you dont have to run the game to browse for players or servers.
Also, Welcome to the forums! Head over to Yodas Swamp, it our off topic forum, if you want to get away from jk2 for a while.
