Is this the newer Grace King? Does it have the wooden or metal carriage?
There is a yahoo group for grace frame owners where you could ask lots of questions. I also did a search here and found many happy owners. I think these are good frames, but the bigger the sewing machine you can put on it, the better. Most of the negative comments I saw were from people dissatisfied with a limited quilting space when using a 9" sewing machine. I recently purchased a used Little Gracie II frame but haven't had a chance to play with it yet. It seems very sturdy. Good luck!!
