I bought a fetish fixation 2007 frame off ebay for $150. It is a cheap frame, but I'm just looking to build a cheap singlespeed (though there is no such thing as building a bike cheaply.....but our cycling team is getting some pretty awesome pro deals this year so that helps). I intend to use my bike for fun and a little training, but I won't be racing on it. I think the fetish will be a nice bike for my purposes.
