I would just build my own, it is cheaper and it is a sump, plus you can design it the way you want it, doesn't have to be a pretty piece of equipment, it is hidden most of the time. I just use a sterilite tub from Wal-Mart. Will be using Rubbermaid stock tanks for most everything when I get around to upgrading my system. Good luck, alot of us like to DIY stuff, so if you need help, I'm sure someone would like to help out if needed.
