POF all the way!!!!
I was on POF from January to April and, man!, that site was off the hook! I never contacted chicks. They contacted me.
I managed to go on at least a dozen dates. I could have went on many more but I didn't have the energy (or wallet) for it. Eventually I settled on a girl I met on there (until I met another one in the "real world).
I've also used eHarmony, and had some success, but the women on there are a lot more serious. I actually met a woman back in 2009 on eHarmonet. We dated for 3 years and eventually got engaged....until she left me. Oh well...
Anyhow, I highly recommend POF. I think that site is the bomb! As long as you have a nice, cool profile that's not cheesy nor too macho, and include a few classy, interesting pictures, have solid first date ideas, you can land a lot of dates and more.
I wish I was single so I could be on that site again! LOL!!!!
