OP, I think this thread is incredibly helpful and I'm glad you posted it! While you didn't get the answers you were hoping for, I think others will learn from it.
I am looking to get a GTP later next Summer - weirdly enough, thanks to my previously snake ambivalent husband, too, who's now totally into it. I'll only do an older uscbb when the time comes. Willing to shell out the bucks, even if it's perhaps artificially high. I'm not experienced enough to take on potential and unnecessary risks of questionable breeding/importing practices. Plus, I want to reward the breeders who are doing it the right way with my dollars. And I'll need at least these next 4-6 months to do the proper research and preparation before I can move.
But that's me, I know we all have to set our principles and boundaries somewhere.
Good luck, and if you don't mind - please continue to update this thread if you find what you're looking for.
