Manufacturing

Generally the cheaper violins are made in large quantaties, in a factory. These factories are usually situated in China or India because of the cheaper labour. The more expensive violins are made out of a more expensive wood and are hand made and they have a much better sound quality than the factory made ones.
The cheaply manufactured violins price ranges from 200 euro to 400 euros. The more expensive ones have a much wider range, depending on the quality of the wood and sound and the history of the actual violin. They range from around one grand to maybe around twenty grand. Most students buy the cheapest violins around because they are not performing, but once they start to perform they like to have a better sound on their violin and invest in a more expensive violin.
Personally myself I bought a cheaper violin because I am not interested in performing and just have it as a hobby.
