The Babylock Jazz does have 12 in. to the right of the needle, but there's not that much height to the throat space. I think that would affect visibility when quilting.
If you don't need the fancy stitches, have you considered the Juki TL2010Q ? It's a straight stitch mechanical machine, with 9 in. to the right of the needle, but harp height is 6 in. Visibility is great. Very reasonably priced too.
