Are you sure there are no scammers IN North America?
Or if you want to advise against SPECIFIC regions of the world to deal with, then please say so and be specific. Otherwise you might do a huge and unfair disservice to honest collectors from outside the US of A (remember there IS a world of decent people and jazz fans out there) who might even be prepared to bear the huge shipping costs for the right item, and/or you might unnecessarily discourage newbie sellers on the forum who maybe have not dealt with buyers from abroad (or maybe even people from abroad at all) before.
In short, please let's be fair.
Seconded
