That is good to know. I spent a good day combing through stuff on here and didn't find any others except one who seems to be a "you gotta be in the club" lab.Two other long standing US domestic sources on this board offer GSO just so you’re aware.
If you wouldn't mind letting me know, I'd appreciate it, but I understand if you don't. Either way, it's always nice to find a back-up in case one source decides to pack up shop.
