As an alternative to a basement dehumidifier, I'm considering an air
evacuation unit. The two units I've found are:
HumiVent-2000 at http://www.dehumidifiers-online.com
Humidex at http://www.humidex.ca , http://www.dry-healthy-basement.com ,
Both systems claim to reduce basement (and home) humidity by
exhausting to outside the moist air collected from the basement floor.
As dryer replacement airs descends from upper floors, a humidity
sensor slows the exhaust fan motor. When basement humidity increases,
the fan speeds up.
If you have installed one of these systems, could you please post your
