Cheaper is definitely a concern, Solar & Palau fans are very expensive.
Good options for 10" and 12" fans though..

Doesn't Can-Fan now have a variable speed 6" fan that speeds up or slows down depending on temperature? That's where it's at...

yes, its the can max-fan 6 334cfm w/speed contrl... high 334 / med 264 / low 201.. runs in the 160-2 bills range...
