I think the issue with the same group of non-related sites being returned from the engines has to do with the footprint. When I find/use my own footprint I see the quality of results increase.
Also, sometimes for targeted harvesting I like to use http://www.outwit.com/ with the 100 results per page toggle. Normally scrapebox will only grab the first 100 links and then move onto the next keyword. With the above I can manually crawl through about 600 links per keyword. Even though this is more manual, I think ultimately I save more time and my targets are better.
