Reproductions are dumb mostly thanks to how they're done. Mostly it's people who think they're helping the community and try to get away with it that way, but they completely fail to make it obvious it's a repro by not putting any signs of it anywhere. They even put the Nintendo Seal of Quality, as if that's supposed to mean something. Makes them no better than bootlegs in that case, and no matter how obvious it is that it's a repro, unless they out text that says "reproducton copy" on it or something like that, there will always be people who fail for it. Add to that the high prices which don't seem to make sense most of the time, and they're just taking advantage of people.
There are some that are done right though, but I can't recall them at the moment.
