Is there a local sewing machine shop near you? Thats where I found my HQ16. After I saw it being demo-ed I went shopping to see if any other sewing machine/fabric shop carried any and then I soon found the pros and cons about them. Personally I took the local store, just incase you had trouble with it. Being a used one, I would hope the person who you would be buying it from would be able to show you how it works and maybe she would be able to help you in the future. If that person can't,(can't remember, or deceased.) then maybe you could google the company of the machine and see if they have any videos on it and also you tube it. Hope this helps.
