Well despite occasionally being driven insane trying to prime the thing I do love my Fluval...You really do forget its there. Although taking it apart is a pain for me, you only have to do it every other month or so, once the flow starts to slow from all the biogrowth it generates, and its so quiet...I got mine for $50 bucks off a co-worker but I think I'd pay up to $100 knowing what I know now. But if you can I'd go for the Eheim or Filstar...From what I hear theyre much less of a headache when its time to open er up.
