I have friends who do and love their machines. It does just what a Statler Stitcher does only doesn't cost the amount of a medium sized house.
I have the HQ16 with the newer bed and trolley system.
There is an online HQ group. I got a lot of help from the HQ people at their site. They are great at answering any questions if you call them. I am sure there is a HQ Educator in your area. HQ can refer you.
