I went to the 1st link and I can tell you already I'd buy it lol I've got 3 Fluval FX5's I'm real happy with that I got on Ebay for $200 each total. Never had a single problem with them but then I never had a single problem with the 3 Catalinas (Ehiem knockoffs) either. Canister filters are pretty basic. I just hate to spend 2 or 3 times as much for a name.
