Juki made a straight stitcher with a 9" throat, and it is marketed under many names. The one I have is the Brother Nouvelle1500s, which is ideal. It is branded by Baby Lock, Brother and Juki, that I have observed and it is called Brother PQ 1500 in the States.Members have said they have bought it for $500-$760. It's about $1766 here.
Hope you are able to trial it as I think it is my best machine.
