Ask HN: What service are you using for display ads?

I'm actually fishing around specifically for alternatives to OpenX and Google DFP.

OpenX (at least the hosted version) is riddle with security vulnerabilities that I have experienced first hand, and Google's DoubleClick for Publisher's is javascript only (meaning, no ads in email newsletters, which is a dealbreaker for me).

What are people using these days? I've seen http://www.isocket.com mentioned a few times around here. It looks like it's still in closed beta though. Everything else I've been able to find via Google appears to be really rinky-dink.

Thanks for any tips you guys might have.
