The best fan I think to get is the Fantastic
"Create a Breeze". Its the basic model, no bells & whistles. They do have
them with t-stats, auto openers, rain sensors, remotes and on, & on.
The Turbo Max fans are great fans, but there mounted externally protruding
above the roof maybe 10-11" and its about 20-22" long. A co-worker and I
did a comparison on the 2 fans and they both came up identical (one was a
little better than the other on the second speed, amp draw wise, but not
much) Hope this helps.
