Do online dating services work well like Match or Yahoo Personals?

I am a man and am back on the market again after a tough breakup. I have never used online dating services before but I am thinking about it now because I am in a new area and don't know many people. Also, I have had enough of the bars and clubs. Would you recommend it? I am a decent guy and would like to meet a serious women for a relationship. What is your experience with online dating?
