Lorenzo - our market is books, and our runs vary from 50 - 2500. My intent is to offer our publishing clients foil and die cutting as an option for their covers. My feeling is that if I offer one service, they'll soon ask for the other. Hence my search for a "combo" machine. On the very short runs, a tabletop hand-fed machine would work. But once we get into 1000+, well, you know... This machine may very well not exist, but thanks to the web and forums like this one, my chances at success increase!
I would suggest that you visit the GraphExpo. There were several such machines there two years ago when I went, high capital investment and square footage, but the throughput and quality were right on the money and seemed to require relatively small training. (If a salesman can do it... )
Good luck.
