$5000 for a fine instrument seems pretty cheap. Would these be good for young people who can't afford $50,000?
I worked on photographing some beautiful older Italian made cellos over the course of ten years. The images are very technical and shot in large format. I think over that time we must have shot over 60 instruments, most valued in excess of what you mention. Eventually it will become a book. During that time I came to know Dr. Ray Carlsen, who established The Carlsen Cello Foundation specifically to get good instruments into the hands of gifted children who may otherwise not afford such instruments. Check the link and feel free to pass it on to anyone you think may be interested. I do not know the current status of the non-profit, nor the parameters for qualification. I have no doubt there may be other similar programs as well. My in-laws (mother and sister) are first viola and cello in the a local orchestra. I will ask them about these carbon fiber instruments and see if they have any strong opinions. From the site and comments there, they sound like a good value, as you suggest. I would also doubt they'd have the same kind of qualities a classical wooden instrument could impart, but then I'm not a musician. The difference in price certainly could mean the difference for many of having an instrument and not having one. Aren't there also programs that lease fine instruments?
