my fluval 404 has been extremely quiet and dependable for the past 3 years. I know you can find it for under $100 at different online sites. It has even cleared my tank from a massive sand storm - took it less than 3 hours.
I don't have experience in any other canister - just know this one is quiet and dependable.
