True, I forgot to mention. Like my friend Alan said, some replicas are even representing the prop better for what it stands for in the series/movies, than the real one that has dings and scratches and wears of the constant use. Some like it, some collectors don't. It depends on the state of the prop. It's a testament for some collectors that the item has some history behind it and that it has been handled by your favourite actor/actress.
At the end of the day, it's a very individual thing of how you cherish the series/movies and how much you like to connect in your own special way with it via a original prop or replica, which is, as mentioned also a budgetary issue. It's doesn't matter how much wear the original prop has, as long as you know the history about it and can tell interesting things about, it is you who values it's uniqueness.
Not owning a prop from your favourite movies doesn't automatically mean you're not dedicated towards the movie/series. Sharing the love and passion to mention the movie or series is proof enough that you love it and want to tell about. Another example: I loove Breaking Bad. But do I own one prop or replica of it? No... there are too many things I'd like to, but again space is my issue here. But I participated in the paper prop thread to show my love for the show.
