I am rather attatched to my Eheim. Low maintenance, super quiet, easy
to prime, (just push the thing on top a couple times) 2 trays for a
myriad of media, plus the chamber at the bottom which I fill with
Bio-balls. However, they're spendy. Fluvals are cheaper, and have
come quite a ways in the effort to remove the negative rep they
had\have. The actually make some nice units.

Any opinions on the rena filstar XP3 ?
