Avoid the paypal thing. Sounds like a scam waiting to happen. Cash is king. Anyone not wanting cash should be suspect. That's just me.
From the RGP discussions I have seen IJ would be a poor choice. I have not played it but still it seems there is a lot of "hate" for this pin. Maybe I am mistaken. But I would visit RGP and do a search for IJ...maybe it's a different version I am referring to..but still worth the research.
Good luck on your first pin. Have you considered older pins like SS or EM style pins? Might save some $$ and ease yourself in to the hobby. Just an idea.
Cheers,
Mike
