I keep coming across the term "clone" here and am trying to figure it out. I would have thought a clone was not a good thing, but it appears they are good, as there are many beautiful ones posted. A lot of these do not look like their "original" ones, like the 15s I have been looking at here. What makes a clone, and what makes it good or not?
