Oh, how important setup really is - walk away from 'factory setup'
One bit of information that is unfortunately not known by many purchasing violin family instruments is the importance (cannot stress enough just how important it is) of a quality, qualified setup. Many inexpensive instruments are sold with 'factory setup' - this means a bridge-shaped object, and poorly fitted soundpost, untrimmed nut and saddle, and a fingerboard that could serve as a washboard in a pinch. To make such an instrument playable, expect on paying a qualified local luthier $100-up, and be sure that you consider it when you are looking at the potential purchase, as it is a real part of the cost, and absolutely necessary. Feel free to contact me for tips or recommendations for your local luthier if you have trouble finding one.
