PedroLlama,
What I am about to say is not only because I work for Heidelberg. I have been in the industry for 33 years and have not only seen many types of printing presses but have also ran quite a few before going to the service side for Heidelberg.
Of the machines you have mentioned, my favorite, hands down, is the XL105. It is a technological piece of wonder. Before Heidelberg built this machine, customers, press operators and service personnel were given a wish list of the things they would like to see on a press if they could have it. The XL105 was the result of those interviews.
It is a departure from the SM line of equipment in its design. A majority the customers who own these machines run them at 18,000 iph and ask us if we can make it go faster. Parts of the machine, like the delivery gripper bars, were tested in a wind tunnel in an effort to cut down on turbulence. In my opinion it is the Enzo Ferrari of the sheetfed equipment Heidelberg has to offer.
That being said the CD and the SM machines are also fully capable of producing quality products at high production levels. The real goal is to match the equipment to your customer's actual needs. Why buy the Ferrari when a Porsche will do?
Heidelberg is not going anywhere and we will be able to support the equipment for your customer at their request long after it has been installed.
I will see what I can do about your request for assistance and get back with you shortly.
