I know that many people have the table top frames and enjoy them. I had a handiquilter and used it with a Juki TL98E. That machine has a 9 in throat space. I make mostly bed size quilts - twin size up to King size. I have to say that I found the quilting frame with my Juki less than desirable.
Because of the size of quilts that I make, by the time I got past the middle of the quilt, I was only able to quilt a pattern that was 3 or 4 inches wide. I found this to be very limiting.
So I threw away the frame and just FMQ on the machine in my quilting table using the 'scrunch' method. This way I can quilt block designs, etc and I am not limited to how wide a design I can quilt.
