We did the same thing, My husbands choice was a Gammill for me. He researched and for the money and the warranty and the quality. Gammill was the way to go. I have the premier. I am not into the computor generated quilting. I want to quilt myself. I can always add the computor later.
My hubby is an electrician and mechanic, he can repair anything except the cat. lol So truly trusted his choice! We attended several quilt shows and tried them all. The seller for me was little vibration compared to the others. I have had my machine for three years now. Love it! Happy shopping to you...
