You will love this machine! I have the 1600P-DBX and am amazed at how much quilt I can get under the arm. I am FMQ'ing a 90 inch wide lapquilt and have had very few problems getting the quilt in place on my new machine.
I have had one issue with it, thread breakage. I have found that the bobbin area needs cleaned often. The needle needs to be replaced often. And the tension needs to be loose, real loose.
I hope you enjoy your new machine as much as I enjoy mine.
Congratulations!
