Well, had the Sapphire 870, and the stiching on the stippling was terrible. I brought it back and the manager adjusted it , and still left a lot to be desired. So having the designer SE, I returned the sapphire and bought the Mega Quilter. I am so happy with that one. For less then a thousand, I have a super machine, and can do my own quilting, I would assume to a king size.
