I am regrettably getting ready to move and will be selling my 15000 , along with others. My husband is Stage 6 Alzheimer’s disease.
My machine is upgraded to the latest version.  It has very few hours. If you want to talk with me, contact me at (sewnqlt21842@...) I guarantee you, you would be very happy with the price. 
Just let me know.
