I have never inquired about top dressing equipment until now. What are some brands? What should I look for? What are price ranges? I just basically want to know what to look for in a top dressing machine, and what brands there are. I have an acquaintance that does sanding, but I'm sure I would freak him out if I were to ask him anything about it. He's scared of competition. But that is somewhat of an oxymoron here in Atlanta.
