I have changed my set up since then, but if I needed a fan I would go with one with a squirrel cage design and an external motor for quiet operation. Good luck!
Absolutely stay away from the big-box in-line fans. I bought two of the worthless things and they were fine when they were out of the box and not installed. After I installed them and they had some resistance they pushed very little air. When they wind blew outside, I could hear them slow down. I could hear them all the time because they were LOUD!
I, too, went with a squirrel-cage blower tied into the duct work. Takes a little more to get it installed, but well worth it. Moves an enormous amount of air, much quieter, and I can run one blower instead of two fans.
