Hi,
i always head very well feedback about the JBL. (you should be ok also)
I'm the Eheim club, more specific the classic club.
In my opinion, a fiter, should be simple and the classic series are just that.
Not many things to break, very popular and easy to get spare parts.
I have 2211, 2213 and 2215 (more than 12 years).
i've watch other series (pro and ecco, i have one ecco) but they have more things to break and much more pieces (more chances to go something wrong).
This is my advice!
Cheers
