+1 Sugino RT 110BCD crankset. Thats the way I would go. I used vintage MTB rings on my Lotus road bike, 47/35. (Used the two larger rings off the MTB crank (donor bike), reused the Lotus stock crank arms) .
What bike? I have three compact cranks on vintage bikes right now. A modern Tiagra Hollowtech II style, a modern Truvativ, and the Sugino RT above. It depends on the bike. I think the Tiagra looks fine on my Prologue, but it would look way out of place on the Lotus. Just one guy's opinion.
