If you decide on Hinterberg, you should probably give them a call first. For the stretch frame, there were two upgrades I know of. One was an upgrade to the carriage, I think to allow for the Voyager to use a stitch regulator; I'm not sure if that carriage would be necessary for your machine. The other upgrade was, I think, the addition of a center post to the frame to keep it from distorting when quilting large quilts.
