Only the Real Thing? Or Reproductions Okay? Where Do You Stand

It's a hotly contested subject in most industries, especially fashion and design.  Is it okay to buy reproductions or "inspired by" pieces?  Or is it a no-no?
There are so many fabulous furniture designers that I love, Jacobsen, Saarinen, Knoll, and Gray.  The problem. Budget.  I'm don't yet have the savings that allow me to invest in an authentic piece.  Does this mean that my home should go without a piece that I love?
It is undeniable that designer furnishings can make a HUGE impact on your space, even if it's just one piece.

I actually have one of these rocking chairs in white....
but I bought it a long time ago before I knew that it was an imitation of one of the most famous lounge chairs!  I still have it and still like it, but I know a lot of designers would cringe.
So, what are your thoughts?  
If you love a design that isn't accessible to with your budget, are you fine with having a reproduction?  
Do you buy authentic only or go without?
I'm not sure how I feel about it, but I think that until I decide I will try to find beautiful, well designed pieces in consignment and antique shops.
