Cannondale, Schwinn and Bianchi all make nice bikes. I've worked with some of the Cannondale guys and they are good people (
Cannondale Supports AIDS/LifeCycle 7 to Record 11.6 Million Dollars) and they make a nice bike.
I think you should go to your local bike shops and ride different bikes to get a sense of what you want: traditional road/race bike, urban cruiser, touring, single speed. Unless you are going to be racing, the traditional race geometry and aerodynamic riding position may not be what you want or need. you might be more comfortable with flat bars and a longer wheel base. Good luck and welcome to cycling.
