I actually don't mind the Kontera ads. You should do those instead of the large popup things!
This is Jonathan from Kontera. We've found that most readers agree with you In a recent study by comScore, the internet marketing research company, they found that users find Kontera in-content ads to be one of the least intrusive forms of online advertising.

An addition advantage of Kontera is our Synapse engine, an algorithm that rather than just scanning for keywords like other, can read your webpages for actually meaning. This added level of contextual understanding is how we can provide publishers with the most relevant ads for their content, leading to higher CTR and better CPC.
Kontera also features an exclusive ad inventory with ads from some of the biggest brands in the world including Microsoft, Olay, Toyota, Jillian Michaels, AT&T, Yoplait, Blackberry, Fannie Mae, and many more. These premium, often Rich-Media ads are the most attractive to site visitors, offer the highest possible CPC, and can only be found on Kontera.
