I've gone through multiple storage solutions over the years, starting with a home made (from 1x12 pine) unit I built in college to a cherry wall unit. I just installed the Ikea Expedit shelves and think they're the best. What I like about them is they are compartmentalized in 12" cubes so the LPs don't bind up as they do in a longer shelf. They are attractive, easy to assemble, and the price can't be beat.
I installed two of
These . I did make one mod - added a plinth with 4" legs to get the bottom shelf off the floor. I will probably be adding a stop to each shelf too to prevent the lps from sliding back (since the shelves are 15" deep and have no back they become uneven.
