I bought an Innova 26" with lightening stitch in August. I agree with Innova18 about ease of handling and great stitches. I also love my dealer. She taught a wonderful 3 day course. She is prompt about answering emails and answering my questions. They even made a delivery to me when they were in the area for another customer.
I learned on a Nolting and used a Gammill (both without a stitch regulator) rented by the hour at my old LQS. I also tried a Tin Lizzie and an HQ before deciding on the Innova.
