I don't know "Black Rose" but from what I have seen posted about him he seems like a good guy. On the other hand I live about a hour from M&P Amusements and rarely have I ever talked to anyone who has bought from them and had a good experience.
Even if you pull up old post you will likely see what I am talking about with M&P. I hate to be negative towards anyone in the hobby (or business) but I do have to agree with Black_Rose. Next time you are looking for a pin you might want to check in with him and at least compare.
In any event glad you are enjoying this great hobby!
