I'm sure they still make heavy use of the Bing API, but have since expanded their range of sources to soften the blow somewhat. They're now getting results from Blekko (who run their own index), and are I'm sure they've been building out their own index. There's a full list of sources here - http://help.duckduckgo.com/customer/portal/articles/216399-s....
We also don't have any pricing details for higher volume usage of Bing, and DDG are in a much better position to negotiate a better deal these days.
I haven't started using it yet, but they claim it offers only slightly less accuracy with access to all of their libraries.
If Amazon sorts out the other issues EC2 could be really great.
