BPA Free Bottles?

I have been debating on this whole new BPA free thing. I am sure you have heard about it being in water bottles, tupperware and of course... baby bottles. The new tupperware I just bought a few months ago of course is labeled "7", and the new baby bottles I bought are not BPA free. For a while, I thought it was just a fad, a designer way to get you to buy new stuff.. but now I am starting to hear more and more about it and feeling like maybe I should shell out the extra dough to get BPA free stuff. That means new bottles, a new pump, new tupperware. What do you think?
