Just wanted to stop in for a minute and speak from personal experience, so far. Those new Quiet Drive set-ups are amazing. I have to walk right up to the tank to hear the faint humming of the motors as compared to the old MP40s where I could hear them 15 ft. away. On top of that, they're more powerful and cost much less than the older models. Not sure why Ecotech decided to drop the price while increasing efficiency but I'm not gonna look a gift horse in the mouth. Anyone else using these?
