has anyone ever tried one of these and how did they go cost wise compared to making your own sump
Can't say I've seen them around but geez they look interesting don't they, I like the setup.
Any DIY but the simplest project turns into a shambles for me, so I for one wouldn't mind seeing the price of them when & if they hit Oz.
