Good luck, Barty. I bought my G70 from Bill Loos @ Southland Music in Taylor. Last I saw, he still had one on display. Hammel music on Middlebelt in Livonia also has a ton of G70s. Tell Linda or Bill I sent you and you'll get treated well; they're both great people to deal with. But that's about it. If you find any arranger dealers, let me know, OK?

ps - I hear Huber-Breese used to sell arrangers, but I don't know any more.
