There is one supplier I know of that is legit.
They are listed heavily in several trade publications and they are known to frequent US trade shows. They have been in buisness for 11 years. I have done a little research on them and I cannot find any proof that they are selling replicas or fakes. But I do see alot of info about them online. Which is a good sign.
