A good point.
My own feeling is that I would like to use the instrument enough to build up my own patina.
Like with the worn look jeans, it only looks good if the wear is genuine. Stone wash is only an approximation of the wear that an old pair of jeans gets through being broken in by one individual. The wear patterns are unique for that individual. Most people don't see that sort of detail. That or they choose not to. Then again, it may be that they just don't care... and really... why would they?
