Well, I am one of those minifig sellers. I sold over 10,000 minifigs on eBay last year. I am not sure why people think we are rip off artists or such. We provide a product and service, that is all. Demand justifies the price, as well as the risk involved. We need to fork out the money to buy the sets from Lego, and are often stuck with leftover ships or pieces that there is not much demand for.
Anyways, I don't mind if Lego decides to start selling some figures this way. It is annoying if you stock up on a figure, and then Lego releases it in a magnet set for cheaper than your cost, but that is life. Overall, I think it will help my minifig business, and will actually hurt Lego's sales. I am not sure that many people will buy the new Dooku ship now that he is available in the magnet set....
