Hi all. I'm a complete beginner when it comes to fixed gear bicycles. I'm going to college next year and I want to buy a new bike. I think I want to go fixed gear because I want something lightweight and simple. What would be a good option for a complete bike? I'd buy used or new depending on availability. I live in Lexington, KY currently and am going to Chicago if that means anything. Something that pops up fairly frequently on craigslist would be cool. Thanks.

edit: how does this look? http://lexington.craigslist.org/bik/1161652357.html
