Eheims are good. Mine is 5 years old and has taken plenty of abuse and still works fine. I expect at LEAST another 5 years from it. I also really like Fluvals. The maintenance is very easy. To disconnect the hoses, you unplug the filter, close a valve, and flip one latch, then you're free to open it up for cleaning and other maintenance. Much easier than my Eheim (although it still isn't bad either)
