Just do a search for SPAL FAN-PWM on yahoo and you can find them. I saw one for as low as $60 + shipping. Their on ebay too. Don't know what the price is there. Seem like the best set up. Personally, I left my AC fan on and used the ProComp 16" and everything seems to work great. I'm using a different controller, but I may get the SPAL after Christmas.
Tell your wife you want one for Christmas <img src="/forums/images/graemlins/baby.gif" alt="" />
