Another vote for Brother PQ1500S machine. It has a 9" throat and will sew at a very high rate of speed. I have it on my home made quilt frame (10') and it does a wonderful job. I am still in the learning curve with it as far as machine quilting but I do like it for what I am using it for. This machine was highly affordable and appears to be very well built. No frills with this machine, just a heavy duty sewing machine, it does have an automatic thread cutter and needle up and down control. I did add the Grace speed controller to it so that it would be more convenient to use it on my frame carriage. Before I mounted it on the frame I did piece several quilts with it just sitting on my sewing room counter and it was wonderful. So either for piecing or using it for machine quilting I feel it is a winner. Good luck finding a machine that you love!
