I have a total of three Eheim 2217's and one fluval 105. Love the Ehiems but the parts availability does kind of suck. I broke a valve during a middle of the night filter change once and had to crazy glue it together for the night then drive an hour in the morning to pick up parts. The next day I bought a Fluval for a smaller tank and its okay. Its on a heavily planted tank and the flow dies off really quick but no other real issues.
