I would definitely buy the HQSS, if I had the resources on hand (old rambling house....constant renovating arrgh). I have been researching quilting machines for some time and the thing I liked about this one, was the simplicity of design. I like the fact it's a sit-down type of machine, because of the design simplicity, less moving bits equals less scope for repair/dramas and from what I have been told backup and service is easy to access. The last bit is important to me, because I live in Western Australia and the tyranny of distance is alive and well. I don't think you would regret the purchase and to be quite honest, I have never seen one advertised here second hand, so I'm guessing people hang on to them. Let us know what you decide and of course show us your tops quilted. Happy hunting and ultimately....quilting
