I started using Start page a while back as my internet search engine. It offers various advantages over the others available.
It prevents tracking and data gathering of your search results. There is a proxy server option so if you are in any doubt about opening a URL you can be more sure about being safe. I do not know how they do it but the search is still routed through Google so you get the same level of search results. Google did try to block it in the early days but have now given up.
