Your available stack height will be your biggest factor. If you put the steerer through the HT with the bottom of the tube touching where the crown would rest how much steerer sticks out the top?
Depending on how ornate the frame and what you intend to build it with I would go with one of the C-Record CampI HS. Some of the late '80s early '90s shimanos had the lowest stack heights though.
For me I have been using a lot of Ritchey logic HSs. They are pretty good quality reasonably priced and don't look too bad.
