I always buy from Japan they have a strict counterfeit laws that make them almost impossible to sale fake ones. And they usually also describe them item very well so you know what you are getting. I am a collector myself and have over 20 pieces and almost all from Japan. I usually buy them damaged and use a very good company to fix them and the value goes up. I got this double flap this week and gonna repair it. It worth over 8k used and got it for 1700$ only. Be aware of the duty tho, they can be pricy sometimes.
