I think Condor would be a decent path to go since they're as Crispin Glover said, to be trusted, plus their fixed wheel bicycles are pretty much a bike for life (once they get the right fit for you), especially for commuting on, the price range you mention will get you a decent lightweight and comfortable fixed wheel bicycle.
