[Utah-astronomy] Sept. QST source for RT upgrade help

I'm hoping that Gary Liptrot or one of the other amateur radio operators on the list might be able to help me with this - I'm trying to determine the best way to upgrade my radio telescope so that it is fully-steerable. It's my understanding that the September issue of QST magazine has a good review of available rotators. But, I've been unable to find a way to purchase the magazine without joining ARRL. I've tried the Logan Borders, Hastings, and Wal-Mart as well as amazon.com with no joy. So, if you could let me know where I could purchase a copy, it would be greatly appreciated. Clear skies, Dale.
