I haven't used it but I heard BigSpy was pretty good from some friends.

The best ones are by far Anstrex, followed by AdPlexity. Both cover a wide variety of ad networks and give you a good idea of what is converting and what isn't. They're not cheap, but they're absolutely worth the money. When you think about how much you'd otherwise spend testing campaigns without any insight into what's already working, they can easily pay for themselves.
