this is an industrial model typically used in the garment district.
the best advice i can give you is to go and try it out and see if it will work for you and the type of sewing you do in your life.
i have 2 juki machines a 98Q and the F600 and i love them both but i do not have an industrial juki and i have never wanted one because i prefer their consumer models for the type of sewing i do.
