Bikes Direct has Windsor Hours for under $ 300. I wound up getting a Vilano that works about the same for what you want to do and it was easier to just get an internet bike and have the wheels trued. Beyond that, you'll only have to tighten the bolts to make sure it's torqued properly. Once you break it in, you'll come to love it. The Vilano I have is one of my favorite bikes. It was $ 259 delivered and I had to have the wheels trued, but after putting in about $ 345 altogether, it's riding nicely to this day. June 2010 is when I got it, so it'll be 2 years old this summer. Relatively inexpensive, nobody has stolen it and it's reliable.
