I have used both dom and overseas. My only concern with domestic is what if the source is busted and has your info . You are screwed, no?
I imagine search warrant for records with overseas in far more difficult to obtain.
Just a thought.
BTW: I do like my domestic products just a bit gun shy about info being stored.
I hate to bring it up but if a dom source is busted and facing very serious time would they cut a deal by giving up info or is it more the source rather than end users the feds are after??
