Adding a sump to my 55g reef. Help!

[mandyplo]

Very new to a sump idea, but I am moving my tank from my boyfriends house to my house as he is neglecting my baby. I love it too much to see it go to waste!

So I want to add a sump as I am going to build a new stand for the tank anyways. As for sumps, I don't know whether I want to do a refugium/sump in one or a berlin method?...

Anyways, my question is does anyone know of any websites that build ready-to-go sumps with overflow boxes and everything? Basically just buy the product as a whole, hook it up to my tank and I'm ready to go?

I saw this one on BRS but I don't know if it comes with overflow boxes or if they let you buy those separately, in case some customers want to drill their tank...

Edit: Okay I just read a little bit about berlin vs. refugium. So let me see if I've got this straight: A berlin is just an open system with water coming into the sump from an overflow box from your display tank, passing by the protein skimmer and any other kind of equipment you are going to store in your sump, then entering the return pump area where the water is moved back to your display. A refugium type sump is similar to a berlin, except that there is a partitioned area in the middle of the sump for marine algae such as chaeto to grow and remove nitrates from your water.

So for me, a person with a mixed reef and fish tank, which method would be most desirable? I'm leaning towards refugium but please correct me if I'm wrong.
