Yeah, it was $200, but no fuss setup and it just works.

+1. I've got two now. Easy peasy. For the one that fills my main tank I've got it modded so that the brain of the tunze turns on an Aqueon Quietflow 8000 in the basement. The tunze stock pump had a hard time with 15 ft of head pressure.

My Tunze only failed me once. Not because of the hardware but because of the user. My output goes into my overflow and one time I was floating a bag back there and it moved the tube so it was pointing outside the tank. Once my ATO kicked on it just shot water in behind my tank until I noticed the water around the tank. Oops!
