I think Dave Kirk, Dave Wages, and Dave Bohm all belong on the USA list as well. And probably Vanilla, Curt Goodrich, Doug Fattic, Mark Nobilette, Glenn Erickson, Kent Erickson, Columbine, DeSalvo, Della Santa, Crumpton, Southwest Frameworks, and Simon Firth/Bilenky. And that's far from a complete list (especially if Peter Johnson is still building - I agree with Ahearne, too, and also MAP, Polito). They may not all survive the current "troubles" (Jonny Cycles has already bit the proverbial dust), but that's not necessarily a bad thing for handbuilt bikes in the longer term.
