Do you have the same repetitive searches every day? How would you think about the idea to let Google make the searches for you and alert you with any new sites that appeared since your last search?
All the SEO companies use this every day.
To do that you need to go to http://www.Google.com/Alerts and sign up for an 'Alert'. You will make Google search for you and the results will be returned to you via email.
You can even choose what type of search would you like: News, Blog,Web,Video, etc and how often will it search.
