Interesting thoughts on copyright... What I can can't quite grasp is if there is money exchanged it is wrong but if you make one it's not... Hmmm, let's see so if you could make your own Kermit or Gonzo it's not wrong? .... I think yes it still is because we are utilizing a pattened idea that even though it is for none profit we are still infringing on intellectual property that the owners of the patent won't get a dime for. So the truth is that if ethics and morals are stopping us from get buying one ... Well then they should stop us from making one also, don't you think?
I for one buy as many as I can get my hands on from talented puppet makers

The day Disney desides to sell the real thing I will buy it from them but that will never happen because that would kill the magic of the muppets.. You see they weren't meant for everybody to have, it's kind of if David Coperfield sold his tricks, what do you think?
