They're a scam. They might have some of those 'rare' models in stock as advertised on the website, but getting them shipped to you is a battle. From what others have mentioned more recently, RM will only ship once threatened with a credit card claim, and even then, it's a 50/50 chance he'll respond.
I'll leave you with this as food for thought, he has scammed people out of hundreds and of dollars in the past (and had gone into hiding for a while before reappearing). If you Google his store, you'll find plenty of people sharing their experiences. I'm surprised the owner isn't in jail for fraud or that his business is still operatable with the number of claims opened against him.
