I own one (I also have a '18 Specialissima and a Pegoretti) and I bought it from a chap for just over $2K. Frankly, I think they look really nice; they are the only frames of Bianchi that are built in Italy (my Specialissima was apparently designed and painted in Italy but made in Asia); and I couldn't find anything close to this in my local market.
I think it's fine and it's fun to ride. But I would love to swap out the calipers, brakes and shifters for a NOS Campy set (any suggestions would be welcomed).
In the end I can understand why the purists have an issue with the bike. I feel the same way - a little - about certain vintage guitars and newer ones that are 'relic'ed' and reproduced to the exact specs of the original. But not everyone can afford a $20K plus guitar and it's really about what the bike/guitar does for you.
As Clint once said, opinions are like a#$%holes: everyone's got one.
