kogswell has fixie and road frames for very reasonable costs. $339 for the frame and fork. Only issue might be that they have provision for rear brake cable routing through the top tube. Good if you run a rear brake, pretty goofy looking if you don't I suppose. I've got thier fixie frame headed to me right now, I'll post some pictues when I get it put together. kogswell
