I bought my Innova from the closest dealer (in Washington State) when I lived in Oregon. My in-store training was done on my machine head, set on another frame in the dealer's shop. I knew that machine was working and had a chance to become familiar with it before bringing it home. The dealer also partially assembled the frame, and showed us what needed to be done to complete the assembly, so that DH and I had no problems setting it up at home. I would have been extremely unhappy if the machine had been untested and I didn't find out until I got it home.
