I have gotten an SR2 frame for my Juki but I quickly realized that I am quilting a narrow row....no more than 6 inches across. Also their On/Off switch that comes with the Gracie frame is very temperamental. Great frame for the price....really sturdy. It seems that there are obstacles no matter which choices we make. Didn't think about the depth of the harp space...which is what I think you meant. Huh. May just keep what I have for now. I got the pantographs and laser light for this machine and frame and they work well. Wish the Juki I have had the speed control on it. Hard to get consistent stitch length. Oh well.
