Need an electric fan....which one??
 

Question guys....the stock set up isn't working too good & I'm looking at the Flex-a-Lite fans (dosen't have to be this brand though). Problem is, there are so many different ones with different sizes/CFM rating/etc.......which one to get? What brands, CFM & size are guys using? Are you running a switch or one with the auto. thermostat?
