oh, good, thank you for replying. I will order the 449CFM. Do you use a speed controller with yours? Do you have to buy specific controller, or can I got to a home improvement store and pick up a ceiling fan controller and install that? Or will I even need it.....I want it quiet and want to be able to turn it down when the lights go off.

Thanks Bob! (and thanks to anyone else that can help)
