Looking for a Good Deal on Wireless Internet

I have decided that I should probably just go ahead and ditch the home internet service I am paying for right now. The fact is that I am spending a significant amount of time away from my home in High Point, NC. In fact I am traveling about half of the time and spending a lot of time sleeping in a spare room one of my co workers has at his place in Chapel Hill. He is in the same position as me and showed me a site called http://www.clear4gdeals.com which offers deals on Clear Wireless Internet plans. I am not sure if that is the best place to find a plan and right now I am wondering what you need in order to pick it up when you are on the road.
