Sometimes they can be too cheap. As a Music Educator, I've been appalled at the horrendous abominations which are sold in recent years as "Musical Instruments" to include many chinese violins which the poor children of today are being forced to attempt to play. My friend called a violin shop feller in the USA midwestern town where I used to live, & he absoulutely refused to look at the chinese violin of my friend, saying that even $30 for a replacement bridge was a waste of money. It was my opinion, too, but I did not tell that to my friend. So I called a good ol' boy feller with a fiddle/oldtimeinstruments shop, & he put a new bridge on for $20, showing her his old fiddle & encouraging her to think about finding a better used one, which she did. She took it to him to look over before she bought it, and she then went back to him for a BOW of decent quality, as well as anytime she needed strings or anything else.
