Are Online Matchmaking Sites worth it ?

Hi, I am new to this board, and new to the dating scene. I am looking at joining one (or more) of the online dating sites, and am looking for opinions from you all, as to which are the best and most reliable.

Additionally, I am in contact with my local church, and have been looking to get involved with some "local" organizations. My inclination is that the sophistication of technology today (internet, database matching, etc.)
is the way to go, but I'm looking for opinions and commentary, on the online dating sites that are most trusted.

Would appreciate some dialog on this.

Regards,

Doug
