We have a Danby 70 pt unit that works very well in our lower floor.  The A/C on the lower floor, about 2,200 sq ft, runs very seldom which makes humidity build up during the summer.  The Danby is rated at 400 watts when cycled "ON", but the unit cycles on and off as needed and when OFF the fan still runs but the wattage drops to about 60 watts.  Yes, the power usage is noticable but not terrible and much cheaper than running A/C to keep humidity down.  Dehumidifiers stop a lot of their effectiveness when room temp gets below 65.

Power example:  50% on, 50% off (fan)

  ON  12 hrs X 400 watts X $0.115/KWH = $0.552/day or  $16.56/mo

OFF   12 hrs X  60 watts X  $0.115/KWH =   0.082/day or     2.46/mo

                                                                                                                  Total $19.02/mo
