Ask HN: Ever advertised on a banner network like Fusion?

Ever advertised on The Deck or Fusion, or similar premium micro-banner network? (Micro in terms of size + properties, not traffic.)

I just did a run for my product and got, according to the ad guys, "the best click-through rate of the month" - at 0.78%.

Yowz.

What's normal? What should I expect? I wasn't able to find numbers from any other designer/developer-oriented SaaS.

Thanks!
