Because i have had a fluval 305 already and i think its time to step up, i am one of those people that like to buy the best they can. I think i am going with one fx5 and if i need more filtration i will just add another in the future. and btw redearsunfish, very nice plan. And with gold fish as your stock the filtration you will have will be more than enough. I think you will actually waste more money by getting all those filters and not a fx5, you can get one for $230 with free shipping on ebay, i just checked.
