Having said all that, however, I think there are specific reasons why many artists seek out hand crafted items:

1) As artists themselves, they want to support the art of instrument building

2) Those who seek a unique sound don't WANT an instrument that is guaranteed to sound exactly like a million other ones. They want a unique creation, specifically because its quirkiness will provide a signature sound.

3) Consider the difference between STYLE and FASHION. FASHION is a temporary norm that is imitated by the masses, while STYLE is a unique look that is obtained only by stepping outside the box. Apart from its sound, an instrument is an image accessory. Some people like to surround themselves with accessories that say "I'm different than you are"
