Aggregated PPC report tool

I am looking for a cheapest solution that will allow you to aggregate reports from Google AdWords, Yahoo Search, and MSN adCenter, or at least two of those.
That means you could create report groups where you add a campaign from AdWords and a campaign from Yahoo, so you can see the total spend and other performance values. Then you should be able to drill down to ad group and keyword level.
The end result would be that you see a report that shows cost per keyword at each PPC engine, and the total as well.
Bid management would be a secondary thing. It could be via API or anything else.
Thanks
