The Factory Made Mandolins are wonderful too. There are many Superior Banjos to buy in today's market. The Stelling Banjos are expensive, but they are great instruments I would think. There are other Banjo Builders on the net also. I have listed some Web Sites to find Banjos.
Fiddles are the hardest thing to find in today's market.
Search the Web for a good Violin Maker if you want a superior instrument. On the low end, and when I say low end, I'm not talking about a really cheap Guitar, there is Takamine, and more Guitar makers that have good sounding and playing Guitars. They are a good working man's instrument. And if you need amplification, it is there and quite good. 40 Charts I can remember when there was just Martin, Gibson, and Fender Guitars for sales, at least the good Guitars.
