Rack/shelf for albums - suggestions please


I just redid my basement and the last detail is to pick up something to store my albums. The last shelf system I had was made of MDF and started to sag from the weight. So, thinking of a rack, maybe 4' > 5' wide, same height to hold roughly 400 albums. Prefer metal but not the cheesy metal racks offered at home depot to be used in a garage.
Any suggestions for some thing industrial grade BUT not too costly?

I use one of these (you can see it in my system link photo):

wire cube rack

The Expedit looks nice also, since I might need more shelving soon and woodish rack looks more sturdy...
Another vote for the Expedit. Can't be beat at the price, and it looks much better than metal shelves, imo. Mine has served me very well for over a year now.
Thanks for the suggestions. Can the Expedit hold up to all the weight - fully loaded with albums? Or, will it sag, distort?
Thanks Paul
If you google "Expedit records" you will see many pictures of the shelf full of records and toppled over. It probably has a lot to do with the size you get, how full of LPs yo pack it, and whether you attach it to the wall or not. I wouldn't doubt that some of the toppled over Expedits were never screwed to the wall. From the Expedit product specifications:

"This furniture must be secured to the wall with the enclosed anti-topple device.
Different wall materials require different types of fasteners. Use fasteners suitable for the walls in your home (not included)."

I'm probably going to get some of these, but I'll definitely fasten them to the wall and I might even reinforce the shelves depending on how well (or poorly) built they are.
