Anyone have any experience or opinions on the Techsew GA 1-5R with the servo motor and speed reducer? I am making holsters- never more than 8-9 ounce leather, doubled over. Most of the time, it's 6-7 ounce. It has a clearance of 1/2" under the walking foot, which is just barely clearance for my heaviest leather projects. I like had sewing, but am getting behind on orders, so am looking for a reasonable sewing machine. I wouldn't being using it continuously- only about once or twice a week for a few hours at a time.
