I have an HQ Sixteen for sale. It includes the frame as well as an extra head unit. I believe it is a 12-foot frame but would need to measure to be sure. It belonged to my mom who is now in the nursing home and she is unable to communicate to answer any questions. She kept it regularly serviced and it is currently in great condition. I believe she bought it in 2004. She also bought an extra head unit so that she would be able to quilt while it was being serviced. The whole set up is $4500 OBO. It has been used recently as she has it set up where several of her friends in her quilting group come to quilt.
