Gigablast has made a number of changes and some improvements since I started this thread.
When Gigablast launched their first search engine in 2002 it was mainly aimed for individual search users. About 2 years ago (2006) they started to concentrate on providing search services to businesses. However individual search users could still use Gigablast.
Gigablast has now again started to pay attention to the individual searcher as well as their business services.
One feature you might quickly notice is what they call their Freshness Dating. This makes it possible for you to search for new pages within the last day, last week or last month. I like this feature, but it isn't perfect. But Gigablast says they are working on making it better.
In addition to Web searches, Gigablast also offers image and video searches.
If you like to test various search engines, you might want to give Gigablast a try if you never have or if it has been a while since you last used it.
