Thank you for answer. I know, SINGER build many perfect machines, like my shoe patcher 29k..., and is not a german product. But many of the german sewing machines goes to Clones.
I think a Pfaff 335 Clone is too fine for my work, and i think a Cowboy/Hightex 3200, 4500 is not fine enough for my work. And so i check the Informations of the GC 2603. And, maybe, such a GC 2603 is a good machine to do my work. I search, and i search, but i found only a lonesome Global Machine and no other machine that looks and feel like the Typical GC 2603. You know other Brands of this machine ?
