I learned to quilt on my Bernina and have never had any issue with a smaller throat. I have been lucky with winning a number of awards with my quilts. With my disability, I have drop off from competing in major shows.
I have seen picture of these sit down machines and there is NO support that one needs when sitting to do quilting. You need support on your left side to support the quilt and support behind the machine so that you are not fighting with the weight of the quilt. I really can't see how a bigger throat will make things any easier if you don't have the support that the quilt needs. I don't mean to step on anybody's toes!! What works for one may not work for another.
