I would put an early de rosa right at the top of my list at this point. the early/mid 70s frames are as tasty, or tastier, than anything else out there, then, or now. And they ride to die for. Them low bb shells ya know.
Problem is, there was very little importation of De Rosas until the 80s, so finding an early 70s De Rosa (let alone a 60s frame--talk about the holy grail!), is not unlike trying to find a needle in a haystack...very, very difficult. Masis and Colnagos were easier to see and buy..hence their popularity with us over-the-hill geezers...but I'd love an early 70s de rosa, and every single serious vintage hound I know around here would like to have one too..
The De Rosas that made it to this country in any quantity (far as I can tell) are 80s frames and use cast lugs. Very nice. But not as nice as the 70s iron.
