Thanks,

I've seen that fan. It looks cool. At about $140 and nearly 200 CFM it seems like a sure shot. "Permanently sealed and lubricated ball bearings support the zero-resistance blade rotation" (from Sunleaves website.) Also part of the money spent on the fan goes to Hydro for Hunger. Some kind of initiative to help eliminate world hunger according to the site.

However its not that I don't believe you wman44 but I would still like to hear what other people have to say on the subject before I commit to a product.

Again thanks for the response.
