The Juki is not a long arm. It does have a 9" harp I believe. (havent measured lately :D ) I started at the top but for a queen or king starting in the middle would be great. Must admit at the end didnt have but a couple inches to quilt at a time :)
If I was to get a new machine Id check into the HQ16 I think is the name. or something similar. For me at this time the Juki is great and is a work horse.
