I am sure you will find planet of information on the Giotto around here. A number of people own them, most of them ECM Giotto though as Rocket has recently taken over the Giotto, which there is information on this site about that transition. It is a great machine but I am afraid that $1700 is not the price of a new Giotto, WELL over $2000 (unless it is second hand) if my memory serves me right. For the $1700 mark you would get something like my machine, an Expobar, which is a Spanish machine.
I have no doubt you will get more comments on this.
