Take your fiddle to someone who tinkers with instruments (any amatuer luthier will do) and let him work with it. About 10 years ago I bought a chinese made upright bass. It was pretty lousy, but I whittled and sanded the bridge to make easier to play. I also put better strings on it and voila! it's not a half bad player. When people find out that I paid $200 for it they're shocked. It didn't take much to make it passable. Pay no attention and give no money to the snobs.
I own Martin Guitars worth thousands of dollars but I just recorded my new CD on a guitar that I paid $100 for. Why? 'Cuz it has the right sound! Don't let the snobs intimidate you.
