Both Hunter and Casablanca are good brands. Like most manufacturers, they have inexpensive up through really pricey models. With 8′ ceilings, be sure to get a model that “hugs” the ceiling (flush mounted). A while back, Consumer Reports rated ceiling fans, with most Hunter and Casablanca models tested in the top half of the ratings. Be sure the electrical box can handle the weight! Plastic boxes are unacceptable. Ideally, the box should be designed for handling a ceiling fan. The fans are very heavy.
