I don't have a fan for sale, but there are a lot of folks on this board that would be glad to give you tips, we even have a couple threads going on the Big Show forum that would probably help you out.
As far as a fan goes, go to qcsupply.com and go to their fan section. Their Durafan High Performance fans are $180 right now, and put out just as much air as Sullivan's turbo fans. They had a big sale last year and bought four of them, and I think it was some of the best money we've ever spend on the show calves. You'd save yourself $85 or so by going through QC instead of Sullivan's...just a thought.
