Yeah I regular Maxx Air is about $30, the Maxx Air 850 (with a bigger vent opening for Fantastic Fans) is about $70
I see one advantage to the bigger one, the fan is made to operate with a certain amount of air flow, if you choke down that air flow it will cause the electric motor to draw more amps and work a little harder
I have the 850 style over all my Fantastics
