Using 3rd party for Fan Club

[fishydotlove.livejournal.com]

Hello, I know several questions have been made about fan clubs but I couldn't find an updated one about using a third party service. May I know how many of you have actually used this kind of service before and how reliable are they?

Some that I found online are:
SOSJapan
Fanclubber
Anythingaboutjapan
Onegai-kaeru

Anyone had experience using their services before? Some charge ridiculously high amount of money, but I'm not sure what's the market rate for this since original FC price is only 5000yen

Thanks in advance!


EDIT: Okay so I've registered the service with SOSJapan. They were very prompt and I managed to finish the online registration in half a day. Card was issued 2 weeks later and is now in my hand. All in all, great experience with them so far :D
