That machine has a 9" throat it only allows about 3" quilting space and then you have to roll the quilt. I have that machine payed 900 for about 5 year ago new. I have the grace gmq pro frame. I can do a queen pretty good but it does give me some limit to the quilting patterns. That seems like almost too much money for used. Does it have the stitch regulator with it? That cost about 500 dollars.
