Hee are a couple links to fans I have been looking for, I havnt been able to find any place that carries them yet, but I do think they would work quite well. When I do find a place I can order them from I plan on getting 2 of each to try.

I have been using primarily sanyo fans since 95. Out of the 15~20 I have used I have had only 1 go bad, I believe that they are about as good of quality as you can get from my experience.
