Rychartski (sp), Wittson (sp) (who are I believe the same people) will make whatever you want in either steel or titanium, or there are a number of UK builders who would also do so (for a bit more cash).
Hmm, I hadn't considered Rychtarski but had kind of written off the idea of a UK custom frame due to cost. Might have to rethink now I've looked at a couple of Rychtarski builds. Now to research disc forks that'll take mudguards and racks that'll fit on disc frames etc.
