£550 for mine and I'm chuffed to bits. It would definitely cost a lot more to build.I think if I wanted a fixed/ss bike I would build my own since it would be a much simpler proposition than a geared bike. (Also - ready-built geared bikes seem cheap for what they are, whereas read-built fixed/ss bikes often seem expensive and/or heavy for what they are.)
