Efficient basement dehumidification?

I have 2 standard freestanding units in my basement and crawlspace running 24/7. I want to get something more energy efficient, will last a while, and that’s easy to maintain. I am considering an Aprileaire dehumidifier. Based on this www.energystar.gov/productfinder/…/results it would appear they have a high efficiency rating. Does anyone have experience with these or recommendations on solutions?
