I know this is an old thread, but I did not want to start a new for for this.
I am finally at the stage where I can get this going and I am wondering if anyone here has tried a Maxxfan: http://www.maxxair.com/maxxfan.html
I did not find anything when I searched.
I am sold on the Fantastic Vent after reading many testimonials and great stuff about their customer service, but I also like some aspects of this Maxxfan and was looking for more feedback.
There is some stuff on the web comparing the two, but not much.
