Marinoni are manufactured in Canada and not Italy, though Guiseppe was born in Italy. I have owned three Marinoni, including a custom model. I raced extensively on two of them, though they were re-badged for my sponsor. In my 30+ years of cycling I would say that Marinoni is my favorite brand. They are an excellent frame and you would be hard pressed to do better, provided the frame in question fits you properly and has not been damaged. The Raleigh frames ridden by the many of the 1984 US Olympic team members were actually re-badged Marinoni.

Marinoni made some mid-range models using Columbus Cromor and Matrix tubing. This appears to be one of them and would explain the 105 equipment and relatively low price.
