Glad I found this topic! I'm looking around for basically the same thing it looks like.
Facebook ads is an obvious one that is not on your list.
I'm looking to experiment with adbrite and bidvertiser. I've also read some positive things about Plenty of Fish ads (they offer self serve PPC) and I'm curious about any other major dating sites that offer the same.
I'll keep you posted on my findings!
