Paid inclusion works nicely because it's like SE traffic, but controlled.

Best advice is if you have some budget to speak of, a little here and a little there goes farther for exposure than a lot all in one place.

Also, depends if you're looking to brand, or get traffic to click to joins.

Traffic Dude and Wildline do paid inclusion on Yahoo and it converts well even on live video chat, which is notorious for a longer conversion term than regular content sites.
