Check the Hinterberg website. Their frames come in two different sizes. One fits the harp on DSM machines; the other is for deeper harps such as the Voyager 17 midarm. I know you can't fit a larger machine on the smaller carriage; don't know if the larger carriage works with the usual harp size of a DSM (about 8 or 9", I think). In any case, it's a great price!
