I have one on a 10 foot Inspira quilting frame - I bought them new about 8 years ago I think. It's a very good basic machine for quilting. What all do you want to know?
Mine has been very dependable, keeps excellent tension, and I can use any brand/type of thread with it. It came with dozens of pantagraphs (to follow with a lazer light). It's the only machine I own that I have never had in for a service job. Probably cuz I can oil it and there's no electronics or computers involved.
