I'm looking at a Panasonic Whisperline 340 CFM unit. Price is right at $150. It is designed to pull from multiple rooms and states in the literature that it is meant to be used with a controller. I have heard the buzz with other fans too and it certainly is not something I can tolerate in my setup.
