Five-gallon buckets are cheap or free and can be used to make some of the most cost effective DIY filters.
I have two bucket filters going right now.
The first is a wet/dry full of bioballs with a prefilter in the drip plate.
The second is a mechanical filter for the return. It has a no-bypass filter pad on the bottom (shown) and a tray full of filter floss (not shown) in the top chamber.
I'm sure there are some pretty great designs out there. Let's see what you have built!

You know it is time to take a break when the drill gets hot or your arm goes numb...
