I agree with that. I bought mine from a local shop. They had a used Gammill and I love it. They set it up for me and went through the steps of setting it up and quilting, then left me with a quilt sandwich to play with. I've been practicing since then. I've not had a lot of time with it since I'm dealing with cancer also, but when I get a project reading to quilt, I'm off to the shop with my oxygen, ready to play.
If I have a problem with the machine, which has just been once, but they are right here in town to help. But do try them out first.
