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?

Go metal - Billy Bags.
Will hold 1,000 LP's without breaking a sweat.
Usually about $850-$900 here on the gon, but you'll have to find one locally.
I have both his LP & CD racks & swear by them.
You'll get what you pay for & if your LP collection grows - You'll be set for life!

Look for the 6+ foot tall bookcases that sell seasonally at Sam's Club. Adjustable shelves and deep enough for LPs. I have two. They house most of my 3500 albums. If you shoot me an email, I'll take pics for you.
I built my own racks out of 12" pine, screwed together, screwed to the wall, using simple 1x4 as cleats. I put vertical dividers every few feet across each level to prevent sagging. I gave it all a light sanding but didn't finish it otherwise. It took a weekend of my time, but it's sturdy, smells piney fresh, and looks great in my storage closet. It looks a lot like what you might see at a used record store. Nothing fancy--just built it to fit as I went along, alot like the closets were done in older homes by carpenters before we had built in storage systems. I estimate it could hold 800-1000 lps. Total cost was about 50 bucks. I could take some pics if you want to see. Good luck!
