Hunter no longer manufactures model 21543 and the fan has not been available for quite some time. I highly recommend you consider the Casablanca Panama ceiling fan. The Panama is one of the best performing high quality ceiling fans ever made and has been the industry standard for nearly 20 years. The Panama is a customizable fan that does not come with blades or lights, so you choose them separately to design the fan to fit your needs. The 4-light fixture options are one of the few that still come with standard medium base sockets that can accept 60 incandescent bulbs, although they ship with CFLs. Most 4-light fixtures from other brands either use candelabra base bulbs or plug-in type CFLs (to meet government regulations).
Casablanca recently introduced a special tool on their website that allows you to customize your fan and see how it looks before you buy it. Here is a link to that tool. Any of the fans you see on that site will be equivalent to the Panama, which is one of the choices. When you are finished building your fan, click on the checkout button and it will put your selected options into our shopping cart where you can finalize your purchase. We also have a promotion that will give you a FREE Casablanca Remote Control worth $80.00 when you buy any of the Custom Casablanca fans.Custom Casablanca Ceiling Fans
Here is a link to view the Casablanca Panama directly on our website where you can also select components individually but you cannot see how the completed fan will look, just the individual components:Casablanca Panama
BTW: The Hunter Studio Series ceiling fans are a lower end Hunter fan and they move only about half as much air as the Casablanca Panama...although the price is about half that of the Panama as well.
