I dont know a whole lot about "The Machine" which used to be called "The Man Machine" btw. They may still call it that in Europe and elsewhere.
I like the Estrada and Estrada Pro models but I cannot tell you the difference between them and "The Machine"

There are not many Cinellis out on the road that I have seen. You will get allot of looks when you are riding one thats for sure.
I have a Cinelli Xperience I would not hesitate to buy one again or one of their other models.
