I bought a brand new Fluval 404 w/media for $107 with shipping. It's last years model, but not that much had changed. If I had to buy a new 504 model, I probably would have spent the extra on a Eheim. However at this price, I could buy two 404's and still have money left over. I even considered buying two... just to have on hand for my next tank(which I'll negotiate between 40(breeder), a 55 and a 75.. and you know which I prefer)
