Unless you need the flat surface coming off of the front of them I would just make one using a bucket or rubbermaid tub. As long as you can hide it you can make something that does the same thing for a fraction of the cost.

as long as they're filled with media that can hold bacteria they would be great.

I use the skimmer/bio-falls for my pond.

Crystal clear water, healthy fat fish, super low maint.
