Show Music Magazine

Does anyone know where I can find old issues of Show Music magazine? I'm constantly checking Ebay and have only been able to find one issue. Had a bunch way back, but they seem to have grown legs and left. If anyone knows a good place or has old issues they're willing to sell, please let me know. This was a very important resource for me before the internet made it easy to find stuff on cast recordings.

Loved it so much. Introduced me to so many shows I would never have found in my small town. I had so many of their issues, too.
