i started with a walmart NEXT, then upgraded to an old Schwinn Suburban Road bike. After not using gears much and wanting to lose the heavy steal wheels, i found deals on a front wheel on ebay ($20) and a good rear wheel locally. I loved it. I eventually order a frame from bikeisland.com ($200) and put all my parts from the Schwinn on it.
Mine is a FG and my commute is 18mile round trip no hills thankfully but not at all flat.
