I have the HQ Simply 16 on the 8' frame. I have had it for about a year. I love everything about it. The price was great, and I have no problems with it. The folks I bought it from were so sweet! They came to my house, installed it and taught me how to use it. I use Superior Threads Omni for quilting, and I never have tension problems. I just clean the bobbin often, oil regularly, and have a great time with it. I mostly quilt with pantographs.
