Fluidized bed filter?

I found one for 53 dollars online. It's a lifeguard one for aquariums up to 300 gallons. I'm going to connect it to the output of my power head for the time being, and once I have a bit more money, I'm going to buy a Rena canister filter. It pumps out 250 gallons per hour, and is only about 60 dollars. It's cheaper than most pumps, and also will serve as a good mechanical filter.
