The site I work for, PriceGrabber.com Travel, along with the other aggregators out there can help you if you want to just continue checking for fares on your own. When you enter the dates, these sites will bring back results from many sites around the web in under a minute.

If you want something that will check automatically and report back, you can set up fare alerts at places like Orbitz where they will notify you when a fare goes below a certain threshhold.
