Also, any "whole house" fan owners out there? What do you think of them?

Sounds like you are trying to keep the attic cool (ventilation fan) versus cooling the whole house (whole house fan).
I have installed and used both.
They now make ventilation fans that operate on photo cells mounted on its cap - easy to install - no electrical hook ups. A friend has one and it works great. As far as their overall value - they are well worth the money - they really keep the AC costs down.
Whole house fans do cool the whole house as long as the temp is cooler outside than in - they also pull in the humidity. Sometimes keeping the windows closed on a hot day works better as the house never has a chance to heat up. We have the following unit in our island home (
