It seems that knock-off puzzles is a very hot topic at the moment.

I have some specific questions concerning knock-off puzzles and instead of replying to a thread that will make it go way off topic, I thought I would start a new thread dedicated to knock-off puzzles.

I'm still relatively new to the world of twisty type puzzles with my past experience being the Rubik's brand. I would like to do my small part to help stop knock-off puzzles and in order for me to do that, I plan on avoiding sites that support and sell knock-off puzzles.

Unfortunately, I don't know which sites are selling authentic (original & officially licensed) products and knock-off puzzles. I should add that there may be sites that are selling both (authentic & knock-off) types of puzzles so if anybody knows which puzzles are authentic (probably a shorter list) please list to take the risk out of buying knock-offs from ebay.
