ok... I think you're going to find it exceptionally difficult to get a fixed wheel bike for that price. My advice - hunt down an old racer on ebay then take the derrailleur/gear mech off. instant single-speed. I found an old raleigh 10-speed on ebay for £70 for this purpose. That way, you could probably also afford to get a decent back wheel with a track hub if you then decide you want to go fixed.
