I have the HObby Quilter.......now known as the funquilter by Nolting. I haven't had any problems with it thus far....
I know that the Voyager 17 is also a stretched machine. When they first came out I was on the waiting list for that but never got a call. I was impatient anyway and got the one from Nolting. I have mine on the Hinterburg frame.
Hinterburg, I believe, sells the voyager17 also.
