Did not look at them... how many CFM's on a 6 ? I went the e-bay route and after awhile decided to go with a Tjernlund M-8. They claim to be quiet and produce good circulation for a good price. I'm giving $150.00 for 675 cfm's and it also came with a speed control which sounds nice.

Let me know how your fan turns out for ya :thumbsup:
