I'm quite partial to Marinoni (they are built close to my hometown!). I have 2 of them. A '95 road frame, and a '90 touring. Both excellent.

Mr. Marinoni started building frames in '75 I think. He has now passed the business to his family (I think) and they've adapted to the market with Al, Ti and Carbon frames (and of course steel), after resisting for a long time with lugged steel frames. Anyways it's very good stuff. I doubt you can find better value for a custom frame in North America. However I think making a 67cm frame might be difficult. I suggest you contact them.
