Friend of mine has just put up for sale his Fluval 204 for $20 with no media included, so I'd have to buy all that. Does this sound like a good deal? I don't know anything about Fluval.
Its an excellent filter, and well worth that very low price tag!! You can usually pick up some ceramic media/bioballs and a couple of sponges cheaply on ebay or on the forum.
I run 2 of these at home, since they came out, have never had an issue with them ever.
