1707 Stradivarius Violin. One of my customers is a Russian cellist whose brother - also a Russian, though a violinist - owns a Stradivarius. His is one of the less expensive models, costing him only four hundred thousand dollars. He brought to my office and I got to hold it. Ooooooh. Actually, it was pretty cool. The Strad fiddle pictured sold for 3.5 million in 2006.
