Be careful and to do not confuse the name professional with industrial. They can call anythng professional. If you want a great singer get a used pre- 70's singer.. they are real work horses, and have a stronger motor. They started to reduce the motor's in the 70's and the over all quality. So many 1950 era machines and earlier are still working, and require less maintinience than the new machines and can handle just about anything.
