I've had an Eheim for five yrs or so, and I got it used. Reliable and quiet. Ran a mag 10 for a while and hated it, way too loud. I do use a mag 5 for my salt mixing setup. Run it externally, it runs so hot I got a fan running on it.
Nice! Thats the type of longevity I like to hear about. Soon as my "fun" money recovers from the rest purchases, I plan to pick one up. Thanks for all the info!
