In reply to williemiller: I got a steel 725 frame built by Steve Goff
http://www.steve-goff-frames.co.uk/contact.shtml about 3 years ago. It's an awesome build, he copper brazed the joints, got the sizing perfect, dropped the top tube to give it a tight rear triangle. I use it for everything from a 20 mile blast to 5 day tours.
It cost me £375 at the time but he said he'd be putting the prices up soon. I doubt it'll be much more now though. He also builds carbon frames if you're into all the blingy shit. Bob Jackson in Leeds is a good shout too but bigger and more expensive.
On another note Johnj of this parish is just getting into frame building, might be worth sending him an email.
