I like their membership. I feel MOA has a lot more to offer compared to the other BMW club. Nothing against RA at all, I just prefer MOA. I like having the Anonymous book with me when I'm traveling. I paid for a life membership many years ago, which I don't think they offer anymore.
Overall, weather you want to pay a yearly fee for any club is totally a personal choice. Weather it's MOA, RA AMA, just go to a particular website and check out what they have to offer for the price.
